That question has been skillfully answered here (I hope).
I've known about the sports drink cure (Gatorade, Pocari Sweat) and the water cure (hydrate, hydrate!) for a while. I like the sports drink cure better because it tastes good and when it tastes good, you drink more.
Look at the success of Propel water here in the States for proof of that. Gulp. Gulp.
This is a travel tip because if you hang out in Japan, you will be drinking alcohol (A LOT) and you dun need a hangover to spoil your holiday!
Apparently the burnt toast does work pretty good as a remedy.
A version of this is used in hospitals all over the world in the form of charcoal.
If ever you are sent to hospital for alcohol poisoning or any sort of ingested poisoning, they will flush your stomach with charcoal to soak it all up.
Charcoal or carbon is also one of of the main ingredients of hangover tablets you can buy at the chemist.

By the way.. I think Cryonara (i think tt's the way it's spelt) Artichoke works. They are pills and so far I've not gotten a hangover when i do take em. Pasta and generally stuff with tomatoes actually help a ton too. The whole greasy thing doesn't work for me.
