Although a shower isn't a cure, while I'm in the shower I feel a whole lot better. Old Polish remedy...eat Garlic brine pickles. Supposingly packed with minerals and vitamins which will make you feel better.
I haven't had a hangover since the age of 15. And yes, I've been consuming lots of alchol since then. XD
I officially hate alcohol, but I am addicted to it, I usually just sleep it off and drink lots of water, it helps alot.
