My favorite is RedBull. I drink one a day because i cant do anything without it. It stimulates my mind so i can actually not go insane while writeing a 10,000 line java script.
Although, I love Red Bull. Gawh, I might start drinking one of those everyday for school. I got to get all A's this year, and I'm used to getting C's. Haha
Redbull is alright, Monster makes me want to throw up, Bawls is alright, but Spike Shooters are the best by far besides them being illegal for people under 18 to buy <.< They keep you boosted for a good 5 hours and you don't really crash =D
