I once consumed 2 beers, half a pitcher of beer, 3 vodka/cranberries, three gin/tonics, three screwdrivers, 4 shots of vodka, and 3 shots of gin all in about 2.5 hours. I thought I was dead the next morning. It was my "never again" night that made me wake up and swear off the crazy nights.
*If you don't drink, but do other stuff, subsitute your drug of choice...stoned, rolling, etc...whatever kind of bad night you have.*
