Last St.Patricks day I had drunk around 10 pints of Guinness and a bottle of cider, and I was rather drunk and would very usually get a hangover from drinking so much and not being sick. But inbetween going from one pub to another, me and my two friends went to the off license to get some more beer and stuff, and I randomly bought a bottle of rosé wine. Just as we got into bed to go to sleep, Ant passed out, and me and Pitman randomly talked drunk crap for a while, and I drank the bottle of wine right then before going to bed. When I woke up, I had no hangover. I'm going to try it again sometime to see if it was a fluke or if it really works.
