Before you go to bed when you are drunk, chug a big glass of water and eat a banana. If you don't like the nanners then take a potassium pill, and eat a package of soda crackers. The big glass of water will wake you up in 3 hours so you can take a piss. When you piss, chug another big glass of water. You should wake up after about 6-8 hours with no hangover at all.
