If you are young adult, and your body has never before been exposed to this (1,3,7 trimethylxanthine), then you will feel a "turbo boost" for about 24 to 48 hours straight with almost no let-down time after. After about 8 months of responsible minimum-necessary hit use, Caffeine use will change to a turbo-boost for 24 hours and a recovery time of 48 hours. After about 2 to 5 years of overuse (where I am), and after stimulant abuse, your body will mutiny and burn out, you will drink caffeine along with a quart of water, and instead of a turbo boost, it just makes inconsequential stuff irritate you. It's at that point you should abstain for a week or 2, and your body resets to some extent and it returns you to 5 hours of turbo boost and 48 hours of down time. In my early 20's I was stage 1, in late 20's stage 2, and in early 30's stage three.
