As I am diabetic and can't consume suger in the quantities in energy drinks, I drink about 2 pots of coffee a day, which when drinken black as I drink it has virtually no suger or anything that can be turned into suger by the body.
I require it to stay awake. Which reminds me I need to pour another cup.

For a person who actually like chemistry and has thus far taken four chemistry courses in college, allow me to impress you with this information from memory:
Bawlz and other highly caffeinated products use <b>Guarana</b>. A plant discovered in the Rain Forest not that long ago which has more <b>trimethylxanthine</b> than coffee. (C[sub]8[/sub]H[sub]10[/sub]N[sub]4[/sub]O[sub]2[/sub], white crystalline solid, bitter, acidic) <b>Caffeine is an addictive stimulant alkaloid.</b> Among its many actions, it operates using the same mechanisms that amphetamines, cocaine, and heroin use to stimulate the brain. On a spectrum, caffeine's effects are milder than amphetamines, cocaine and heroin, but it is manipulating the same channels, and that is one of the things that gives caffeine its addictive qualities. If you feel like you cannot function without it and must consume it every day, then you are addicted to caffeine. Caffeine is also administered in trace amounts in drinks, so while the drug itself is very powerful, the effect is barely noticeable. Caffeine and speed are in the same subfamily and are chemically similar. It's molecular weight is 194.19 g/mol. It's functional groups are amide, amine, and imine. One gram dissolves in 46 mL water, 1.5 mL boiling water, and 66 mL alcohol. Caffeine sublimes at 178°C. Caffeine stimulates the central nervous system, heart muscle and respiratory system. It has diuretic effects (increased urine) and delays fatigue. Theophylline and theobromine are other alkaloids, which are also present in some drinks. These compounds are very similar in chemical structure to caffeine. Caffeine tablets such as NoDoz can be obtained without a prescription and are used to increase alertness. Caffeine is also used in combination with painkillers such as aspirin to provide headache relief, but there is little evidence for its use for this purpose. <b>A lethal dose is estimated at 10 grams</b>
Now personally, I've found on a scale of addictiveness observed from others the addictiveness and severity (from worst to least): ethanol > tetrahydrocannabinol > trimethylxanthine (alcohol, marijuana, caffeine)
The bad information that I won't share: I know how to extract and distill caffeine allowing me to get a very concentrated (almost pure) vial of caffeine. While I highly doubt anyone will use the information to kill someone I do fear that I can be used in the manufacture of drugs.
PS: Starbucks does get some degree of popularity because of caffeine's often forgotten addictive qualities.

His number information is a bit off to the high side. 16 gams of pure caffiene is plenty enough to kill you. But then again considering how little a <i>trace</i> ammount is, it would be a ridiculous of coffee or a very bitter single drink. In all likelyhood you'd have renal failure long before you got enough to kill you.

I honestly don't see the point in flooding your system with Caffeine. I think it was Illuminex that pointed this out before, but the function of that stimulant is more to allow you to override pain and keep working without feeling weardown than to keep you up. So if you work some kind of desk job, you need coffee far less than the average layman.

So if its addictive you can become dependant on it I assume, that would explain my need (and I'm sure many other peoples need) for coffee to fully function in the morning, or is it psychosomatic?
wait... it's addictive? Then why do I never 'need' anything like redbull or whatever to function? I've drank a ton of the stuff over the years but it's pretty irregular and I never go looking for redbull. Just every few months I'll usually nip into a shop feeling kinda tired and notice some RB on the shelf thinking "that'll do!". I don't drink coffee or tea, infact redbull is pretty much 100% of my caffeine intake the very rare times I bother to drink it. I think I've had all of 2 cans this year so far <!--emo&:p--><img src='http://www.unknownworlds.com/forums/html/emoticons/tounge.gif' border='0' style='vertical-align:middle' alt='tounge.gif' /><!--endemo-->
I thought consuming over 5000 mg could kill you. Like 40 cups of coffee's worth. Over a short period of time anyway. Also, if you drink caffeine a lot, it becomes physically addictive, like they said. Usually, if you're a heavy coffee user, and you quit taking caffeine, within a day, you can get edgy, strong headaches, tired, ect. But it wears of pretty quickly.
Of course, you can get headaches and tremors from too much caffeine... so I guess headaches for everyone. <!--emo&;)--><img src='http://www.unknownworlds.com/forums/html/emoticons/wink-fix.gif' border='0' style='vertical-align:middle' alt='wink-fix.gif' /><!--endemo-->
Don't mean to double post, but here's an excerpt I pilfered off the web.
<!--QuoteBegin--></div><table border='0' align='center' width='95%' cellpadding='3' cellspacing='1'><tr><td><b>QUOTE</b> </td></tr><tr><td id='QUOTE'><!--QuoteEBegin-->The binding of adenosine causes drowsiness by slowing down nerve cell activity. In the brain, adenosine binding also causes blood vessels to dilate (presumably to let more oxygen in during sleep).
To a nerve cell, caffeine looks like adenosine. Caffeine therefore binds to the adenosine receptor. However, it doesn't slow down the cell's activity like adenosine would. So the cell cannot "see" adenosine anymore because caffeine is taking up all the receptors adenosine binds to. So instead of slowing down because of the adenosine level, the cells speed up. You can see that caffeine also causes the brain's blood vessels to constrict, because it blocks adenosine's ability to open them up. This effect is why some headache medicines like Anacin contain caffeine -- if you have a vascular headache, the caffeine will close down the blood vessels and relieve it.
So now you have increased neuron firing in the brain. The pituitary gland sees all of the activity and thinks some sort of emergency must be occurring, so it releases hormones that tell the adrenal glands to produce adrenaline (epinephrine). Adrenaline is the "fight or flight" hormone, and it has a number of effects on your body:
Your pupils dilate. Your breathing tubes open up (this is why people suffering from severe asthma attacks are sometimes injected with epinephrine). Your heart beats faster. Blood vessels on the surface constrict to slow blood flow from cuts and also to increase blood flow to muscles. Blood pressure rises. Blood flow to the stomach slows. The liver releases sugar into the bloodstream for extra energy. Muscles tighten up, ready for action. This explains why, after consuming a big cup of coffee, your hands get cold, your muscles tense up, you feel excited and you can feel your heart beat increasing.<!--QuoteEnd--></td></tr></table><div class='postcolor'><!--QuoteEEnd-->
And then this bit.
<!--QuoteBegin--></div><table border='0' align='center' width='95%' cellpadding='3' cellspacing='1'><tr><td><b>QUOTE</b> </td></tr><tr><td id='QUOTE'><!--QuoteEBegin-->Caffeine also increases dopamine levels in the same way that amphetamines do (heroine and cocaine also manipulate dopamine levels by slowing down the rate of dopamine re-uptake). Dopamine is a neurotransmitter that, in certain parts of the brain, activates the pleasure center. Obviously, caffeine's effect is much lower than heroin's, but it is the same mechanism. It is suspected that the dopamine connection contributes to caffeine addiction. So you can see why your body might like caffeine in the short term, especially if you are low on sleep and need to remain active. Caffeine blocks adenosine reception so you feel alert. It injects adrenaline into the system to give you a boost. And it manipulates dopamine production to make you feel good.
The problem with caffeine is the longer-term effects, which tend to spiral. For example, once the adrenaline wears off, you face fatigue and depression. So what are you going to do? You take more caffeine to get the adrenaline going again. As you might imagine, having your body in a state of emergency all day long isn't very healthy, and it also makes you jumpy and irritable.
The most important long-term problem is the effect that caffeine has on sleep. Adenosine reception is important to sleep, and especially to deep sleep. The half-life of caffeine in your body is about 6 hours. That means that if you consume a big cup of coffee with 200 mg of caffeine in it at 3:00 PM, by 9:00 PM about 100 mg of that caffeine is still in your system. You may be able to fall asleep, but your body probably will miss out on the benefits of deep sleep. That deficit adds up fast. The next day you feel worse, so you need caffeine as soon as you get out of bed. The cycle continues day after day.
This is why 90% of Americans consume caffeine every day. Once you get in the cycle, you have to keep taking the drug. Even worse, if you try to stop taking caffeine, you get very tired and depressed and you get a terrible, splitting headache as blood vessels in the brain dilate. These negative effects force you to run back to caffeine even if you want to stop.<!--QuoteEnd--></td></tr></table><div class='postcolor'><!--QuoteEEnd-->

Simply because you are only getting irregular doses. I know plenty of people that have to drink coffee or tea every day (I've heard that tea actually has more caffine than coffee in it) or they don't feel 'themselves' and get irritable.
So yes necrotic, you probably have some slight addiction (although that's not to say it isn't psychosomatic too).

I think I've had all of 2 cans this year so far <!--emo&:p--><img src='http://www.unknownworlds.com/forums/html/emoticons/tounge.gif' border='0' style='vertical-align:middle' alt='tounge.gif' /><!--endemo-->

Of course, you can get headaches and tremors from too much caffeine... so I guess headaches for everyone. <!--emo&;)--><img src='http://www.unknownworlds.com/forums/html/emoticons/wink-fix.gif' border='0' style='vertical-align:middle' alt='wink-fix.gif' /><!--endemo-->
<!--QuoteBegin--></div><table border='0' align='center' width='95%' cellpadding='3' cellspacing='1'><tr><td><b>QUOTE</b> </td></tr><tr><td id='QUOTE'><!--QuoteEBegin-->The binding of adenosine causes drowsiness by slowing down nerve cell activity. In the brain, adenosine binding also causes blood vessels to dilate (presumably to let more oxygen in during sleep).
To a nerve cell, caffeine looks like adenosine. Caffeine therefore binds to the adenosine receptor. However, it doesn't slow down the cell's activity like adenosine would. So the cell cannot "see" adenosine anymore because caffeine is taking up all the receptors adenosine binds to. So instead of slowing down because of the adenosine level, the cells speed up. You can see that caffeine also causes the brain's blood vessels to constrict, because it blocks adenosine's ability to open them up. This effect is why some headache medicines like Anacin contain caffeine -- if you have a vascular headache, the caffeine will close down the blood vessels and relieve it.
So now you have increased neuron firing in the brain. The pituitary gland sees all of the activity and thinks some sort of emergency must be occurring, so it releases hormones that tell the adrenal glands to produce adrenaline (epinephrine). Adrenaline is the "fight or flight" hormone, and it has a number of effects on your body:
Your pupils dilate.
Your breathing tubes open up (this is why people suffering from severe asthma attacks are sometimes injected with epinephrine).
Your heart beats faster.
Blood vessels on the surface constrict to slow blood flow from cuts and also to increase blood flow to muscles. Blood pressure rises.
Blood flow to the stomach slows.
The liver releases sugar into the bloodstream for extra energy.
Muscles tighten up, ready for action.
This explains why, after consuming a big cup of coffee, your hands get cold, your muscles tense up, you feel excited and you can feel your heart beat increasing.<!--QuoteEnd--></td></tr></table><div class='postcolor'><!--QuoteEEnd-->
And then this bit.
<!--QuoteBegin--></div><table border='0' align='center' width='95%' cellpadding='3' cellspacing='1'><tr><td><b>QUOTE</b> </td></tr><tr><td id='QUOTE'><!--QuoteEBegin-->Caffeine also increases dopamine levels in the same way that amphetamines do (heroine and cocaine also manipulate dopamine levels by slowing down the rate of dopamine re-uptake). Dopamine is a neurotransmitter that, in certain parts of the brain, activates the pleasure center. Obviously, caffeine's effect is much lower than heroin's, but it is the same mechanism. It is suspected that the dopamine connection contributes to caffeine addiction.
So you can see why your body might like caffeine in the short term, especially if you are low on sleep and need to remain active. Caffeine blocks adenosine reception so you feel alert. It injects adrenaline into the system to give you a boost. And it manipulates dopamine production to make you feel good.
The problem with caffeine is the longer-term effects, which tend to spiral. For example, once the adrenaline wears off, you face fatigue and depression. So what are you going to do? You take more caffeine to get the adrenaline going again. As you might imagine, having your body in a state of emergency all day long isn't very healthy, and it also makes you jumpy and irritable.
The most important long-term problem is the effect that caffeine has on sleep. Adenosine reception is important to sleep, and especially to deep sleep. The half-life of caffeine in your body is about 6 hours. That means that if you consume a big cup of coffee with 200 mg of caffeine in it at 3:00 PM, by 9:00 PM about 100 mg of that caffeine is still in your system. You may be able to fall asleep, but your body probably will miss out on the benefits of deep sleep. That deficit adds up fast. The next day you feel worse, so you need caffeine as soon as you get out of bed. The cycle continues day after day.
This is why 90% of Americans consume caffeine every day. Once you get in the cycle, you have to keep taking the drug. Even worse, if you try to stop taking caffeine, you get very tired and depressed and you get a terrible, splitting headache as blood vessels in the brain dilate. These negative effects force you to run back to caffeine even if you want to stop.<!--QuoteEnd--></td></tr></table><div class='postcolor'><!--QuoteEEnd-->

Simply because you are only getting irregular doses. I know plenty of people that have to drink coffee or tea every day (I've heard that tea actually has more caffine than coffee in it) or they don't feel 'themselves' and get irritable.
So yes necrotic, you probably have some slight addiction (although that's not to say it isn't psychosomatic too).
