After You Drink: Hydrate Again Before You Sleep—& Make Sure You Do Sleep!

Dr. Cox reiterates that drinking water will be immensely helpful in mitigating how you feel the next day, and he suggests a big glass of water before you fall asleep, even if you've been drinking water throughout the evening. Sleep, too, is critical: "When we haven’t slept as much, we haven’t given the body a chance to reset our metabolism. We haven’t had time to process the day physically or mentally."

You’re also more likely to be irritable after less sleep, he adds—which never helps a hangover.
