The main cause of a hangover is Dehydration. Alcohol dehydrates the system. I know. I have an encyclopedia of the human body. The body is what, 80% fluid? Water is the best thing that you could give your body to wash out toxins such as alcohol. Dehydration is the main cause of head-aches. The best effect for a hangover is a counter-effect. You are drinking a toxin, a drug, that the body uses and needs to wash out. Water, fluids are the best thing to give your body. Personally I turn to fruit juices.
