Caffeine

I do not remember the last time I have happily gone through a day without caffeine. This morning I had a Zip Fizz which is essentially a vitamin energy drink which normally make me feel rather awake and focused, but today I just feel normal. Normal is better than the dead I felt when I woke up this morning; however, if a super large dose of caffeine is getting me to normal, I think I have a problem. What are the withdrawal symptoms after you become addicted to caffeine? extreme fatigue, inability to concentrate, headaches....   Wait, it is finals time. I do not have the time to for fatigue or headaches....  Continue with the addiction? One of these day, I'm going to have to stop. But I'm not quite sure how possible that is... on the upside, at least I'm not addicted to hard core drugs or alcohol.
