I have a tolerance for it from drinking it all of my life. I can down an energy drink and be asleep in an hour or two without any alertness, no tossing and turning. I don't drink it as much as I used to, mostly water and tea now. But, it takes a huge amount of caffeine to make me anywhere close to hyper/wakeful after sleep deprivation.

My fiancee, on the other hand, came from a house with a very health conscious mother and never had the stuff. So, whenever she gets exposed to even just a little of it, she's up for hoursss and incredibly hyperactive. It's almost like she's on some mixture of weed and speed when she drinks a small energy drink, no joking. The last time it happened, we got up at six in the morning and she drank one at around ten that night. She was up until two in the afternoon the following day, and by up, I mean bouncing off the walls, having random giggle fits, etc. : x

I prefer juice whenever I can get it. Otherwise I usually don't drink soda unless its free or whatever. At fast food places they always charge like 1$ +++ for even a small soda so I usually just get water or a water cup and fill it with soda/lemonade. I refuse to pay for soda at fast food place because it only costs about 30cents and they charge you like 8x that.

I mostly don't like caffeine so even when I do drink soda its usually non-caffeinated stuff. Its not because it does anything to me because it really doesn't, its just because I like to control my body's drug intake. Who knows what kinda shit they will find out about caffeine when we are all in our 60s and have been drinking it for years.

Caffeine blocks adenosine receptors in your brain. Adenosine makes you drowsy, and since caffeine's structurally similar to adenosine, it fills up the spots so you stay awake and not sleepy. Tis also increases brain activity, making your adrenal glands release adrenaline, making your heart rate go up and feel energized and alert. Oh, and it makes your brain release that stuff that makes you feel happy, forgot what it's called. Some studies also showed that caffeine makes your capacity to do mental and physical labor higher.

Long term affects happen when all the good stuff wears off. Then you start to feel tired and sleepy, but it will still be harder to sleep since caffeine's half life is like 6 hours, so there will probably still be caffeine in your system. Then you'll probably drink more caffinated drinks to feel good again.

Only bad part is if you stop after drinking caffeine all the time, you might get headaches and feel tired all day. Of course, this varies for everyone, depending on bodyweight, etc.

sounds like the best thing to do is drink Caffeine as a drug when you need a temporary boost to help you stay awake/alert, but to avoid being dependent on it to avoid withdrawal symptoms and potential long term health problems.

I don't like coffee that much, i do drink lots of water and tea (no soda either). When i'm really tired at work i'll drink a cup of coffee, it works for about 2 hours for me. But i try not to make it a habit, otherwise the effect will be gone.

energy drinks are so terrible for the human body. they not only throw off its normal balance (like energy levels) but they put it to extremes which is obviously bad. those people (ICP faggots mainly) that chug this shit are gonna have an early grave.

I like premium-cola, a german softdrink with 250mg caffeine/liter (Coke: 40mg/l) which is the legal maximum here. C-c-can't c-c-complain a-about any aftere-e-e-effects.

I only drink water and milk regularly, but a few cops of cofee now and then. No side effects except from the warm fuzzy feeling

MuShu - Dopamine?

I don't drink coffee or tea ever, and rarely drink soda. When I do drink soda, I don't find that it ever effects my gameplay/alertness... maybe I don't drink enough of it.

They had here a really cheap promotion on cocacola and I bough like 8 bottles (1.5L) and drank 1/day after that I didnt have any coffein and had two really shitty day, I just wanted some coffein but I just managed to fight the temptation.
It was the first time I felt the effect of coffein, usually I had the opposite effect. My head hurted from drinking too much coffein not from withdrawal.
Anyway now I minimize coffein drinking but I have nothing against having one coke once in a while, I just dont want to be dependent on it. (Thanks god I dont like coffee

).
Also I drink a redbull or two if I have a really hard night ahead, like I have to organise a party then bring back everything at 8am after the party and I havent slept. Redbull works perfectly for that, I am awake and able to carry large stuff around as long as its not too mentally challenging.
Coffein doesnt improve intelectual performance thats for sure. Mostly its sleepyness which kills your performance...

It tastes OK, although many people don't like it.
