The best way to cure a hangover in Las Vegas is to breathe the oxygen pumped into the casinos

Actually, the best thing to do in Vegas if you're hungover is to go down to the casino and start playing some cards or go to the sports book because they pump oxygen into the casinos. And so if you want to not be tired anymore, just go down there and breathe that thick-ass air, and you'll be okay much faster than if you got an IV.
