The most I have drank?
Once I entered a drinking contest and had 26 longnecks of Coors Light in a little over an hour... that was bad. I couldn't eat for the next 4 days. I also stayed away from beer for the next 3 months becuase of that.
Another time I had 10 well drinks, 3 beers, and 2 large shots of everclear and I was royally fux0red... was at a badass fraternity party. Peer pressure led me to take the shots with everyone...
The last time I drank alot (I finally learned my lesson) was when I was at a party at a lake, and I ended up drinking a whole bottle of Captain Morgan's and hooking up with some hot chick who called me "the captain." I don't really remember this at that point, but everyone told me the next day... I didnt like how that happened, and could have been much worse considering the circumstances...
I never drink much anymore... only 2-3 drinks at most during fridays and saturdays only. The wonders of college.
EDIT: I remember one more time, during my pledge semester where we had to drink a whole 1.75 of alcohol... mine was Seagram's 7. I was the last pledge to pass out, and I woke up the next day on the couch in the chapter room with the empty bottle in my lap having missed all my classes.
