when I drink like friday/saturday with my boys or parties or whatever everybody buys their own fifth. Right now I can prob. drink a fifth and a half of Jack in a nite and be shit faced, but not puking. 21st birthday I did 36 shots if I remember correctly...but I threw up and tried to fight all my friends...sooooo that was prob. too much.....I dont even drink beer anymore...it takes too many I get full before I get drunk......I know...I have a problem.
