Of course, hindsight is 20/20, but the next time you're planning on hitting it hard, do some maintenance first. According to Dr. Elizabeth Trattner, a Florida acupuncturist, eating a healthy and substantial meal before the fact can be a big help.
"Make sure this meal has both healthy fat and fiber to delay transit time in the digestive system," she told me. "By having both fiber and fat, food will stay in the stomach longer and will keep you from getting completely smashed like if you went with an empty stomach." Trattner also advises alternating water with alcohol, so you don't end up drinking too much and getting more dehydrated.
Another prep trick that could result in a better morning-after: fish oil. Because it contains omega-3 fatty acids, which reduce pain and swelling, taking it when you come home from a wild night might mean you wake up without a headache, thus reducing the damage alcohol causes in the brain.
