Well I don't get hangovers as such.. Occassionally I wake up feeling a little odd in the stomach area though after a few too many pints of guinness. I find that scrambled egg on toast does the trick, I believe that Egg is supposed to increase the speed in which alcohol is broken down, I think thats why you put a raw one in a bloody mary (also good for fixing a hangover).
Having said that I have 2 other things to mention, the first a lesson the second a joke:
1.) Lesson:Never ever drink half a litre of tequila in half an hour... Much vomiting will ensue while you are unconcious.
2.) Joke: What do you call a bloody mary with no vodka in it? A bloody shame.
