Not alot regularly, maybe a six pack a week at most. But a special event or party, I pretty much overindulge.
Last party I overindulged big time I drank 11 beers (Australian beer mind you, so 1.5 standards each), maybe one or two drinks from a hip flask my mate had. The it went downhill when I found an abandoned bottle of rum, and we started playing "I have never" (my favourite drinking game, but there has to be chicks). Problem is my mates know some of the crazy stuff I've done, so I drank a lot. I blew .05 in the morning and my mate had to drive my car home.
