glass of water every 3 drinks and if you can smash a bottle of those isotonic drinks before bed you should wake up sweet as

And if you're not too sure about spewing when you're in bed then force yourself to spew lol You'll wake up like nothing happened lol
What's happening is that alcohol dehydrates you so if you drink a lot of water/isotonic drinks during the night hangovers will be thing of the past lol
