My old hangover cure, from when I was in the Navy:
Before going to bed, eat 2 pieces of bread, take two aspirin, and drink 2 glasses of water. When you get up, drink a bottle of V8 juice. It won't make you 100%, but you'll definitely feel a lot better when you wake up, than otherwise. And by noon, you should be feeling good enough, to bite the dog that bit you.
