i use caffeine the same way most people use beer. if i'm having a really bad day, i'll get as much as i can in my system. for example, a couple weeks ago i asked this girl to homecoming. turns out she's a lesbian. well, i had had a coke for lunch, and a bottle of bawls during the period after lunch, just so i could get all pumped up for when i asked her. then after i found out, i downed about three servings of penguins, went out to dinner and had two or three glasses of coke, then i got a nice double espresso after dinner. needless to say, i had a tummy ache that night.
