Eat a banana, and drink a glass of warm water with one teaspoon of kosher salt and one tablespoon of sugar.

Gatorade and something greasy always fixes me up pretty quickly

~18cm cucumber before drinking and one half way in. I haven't had a hangover since this discovery. Sorry I can't be much help for the hangover part :/ Good luck!

I was visiting our public swimming pool, and as I was already there: sauna. But cautiously. Got rid of a really bad hangover with a sauna and swimming in a few hours last spring. Works like magic. Plus of course large amounts of water and fruits.

The Bourdain method. Hands down.

Complain and then do it again next week

I don't

Pedialyte, ibuprofen, and weed. I don't drink much anymore but I used to get the most wicked hangovers that would leave me puking well into the afternoon the next day and unable to keep even water or pills down. Weed is the only thing that helps in that situation.

Really good, flavorful, salty beef jerky preferably handcraft small batch type stuff works for me, along with several glasses of water. But what do I know? I only spent 30 years in intensive hangover prevention and cure.

Don't drink.
