H2O is a must. As you likely know from the frequent trips to the bathroom during a night of debauchery, alcohol is a diuretic and can cause dehydration. Before falling into bed, down 16 to 20 ounces of water, says Daniel K. Hall-Flavin, M.D., a consultant in addiction psychiatry at the Mayo Clinic. And the next time you go out, he recommends ordering a glass of water with every beer—and alternate between the two to replace lost fluids as you go.
