you definately need to drink more. peoples tolerances to alcohal very alot but one of the most i've ever drank was 1/5 of vadka and needless to say i was severely fucked up. me and my friend took the half gallon of vadka challenge and didn't even come close. together we finished maybe a little over half and i was unimaginably drunk. but i also come from a long line of alcohalics. and for some reason its still legal while weeds not. i've never smoked so much i passed out on a cement floor and pissed myself all night. but 3 shots of anythign isn't really enough to get u drunk.
