Real hangover cures?

I read that a hangover is a chemical imbalance in which alcohol displaces salts and electrolites, or something like that. For what I have read or seen, either gatorade or drinking serum are good hangover cures as they replace what was lost, which one of the two is best?, or is there something better?. Please... show more I read that a hangover is a chemical imbalance in which alcohol displaces salts and electrolites, or something like that.

Please avoid stupid or superstitious responses such as "don't drink", or "try tacos"
