For a friends bachelor party weekend I knew we were going to be boozing for 3 straight days and I get horrible hangovers. I drank highly distilled vodka (grey goose, level one, etc) on the rocks with an orange wedge squeezed in it. I also pounded gatorade in the mornings and before we went out every night. Didn't stop the hangover but definitely lessened it and kept me partying all weekend
