I'm 160 and after 3 hours of not drinking I normally sober up a bit. I'm with you that 5 hours or so seems to be a good number for me. I can't do a 9am-2am drinkathon-- met some med students that managed that the first game of the year this year. Hats off to those guys, an impressive feat.
It's that Husker blood, makes you a pussy T3.
