If i am drinking shitty cheap beer, it is usually about 15 or so. If I am drinking micro brews, then its about 8. And probably about 10 mixed drinks will do me in nicely. I still have yet to pass out or puke from drinking. Back in high school I once came across a case of Absolut Vodka. I was 15 and had 18 liter bottles of vodka. I could down a bottle of vodka in a night and still be able to stumble around town. That shit would kill me today though.
