technically, during century club, you're not allowed to lose any bodily fluids, or it doesn't count. that means no puking, pissing, crying, bleeding, etc. i did it successfully, and no being allowed to piss was the hardest part by far.
yeah, 40 beers in 12 hours is under 4 per hour, but that's 12 hours of drinking. you have to be a fucking champ to be able to do it. i mean, i've drank for over 12 hours straight before (personal record is 18 hours, 7am - 1am), but i didn't drink at nearly that rate.
