haha i do the same thing, but that's cause beer fills me up and hard bar doesn't. plus i drink hard A way faster (and not just when i'm doing shots, duh) which leaves more time for things like dancing, which i'm good at when i'm drunk, i swear. also, ever since my 20th birthday (beginning of august) beer hasn't really agreed with my stomach. i can't really chug it any more which really really sucks, but that's what i get for going overboard (i puked at the bar at 10:30 and kept drinking, puked when i got home at 4ish, and then puked pretty much straight from 8:30am - 1pm. i literally could not drink for 2 weeks and couldn't binge for a month, and the day after, when i was watching TV, alcohol commercials made me puke).
at my peak (towards the end of my first year of university) i could throw back a 2-6 (or a "fifth" for you yankees) and be drunk but not puke or anything like that. now i drink much less often (and therefore spend way less money) and i can't drink nearly as much in a given night (thus saving me even more money). oh, and i'm like 160 lbs i think. maybe 165. i, uh, drank a lot in first year.
