Eat amino acids . Amino acids are the building blocks of protein. Like vitamins and minerals, they can also be depleted by use of alcohol. Dr. Blum says that replenishing amino acids plays a role in repairing the ravages of a hangover. Eating a small amount of carbohydrates will help get amino acids back in the bloodstream.
Amino acids are also available in capsule form at most health food stores.
Have two cups of coffee . A couple of cups can do a great deal to relieve the headaches associated with hangovers. But don't drink too much. You don't need coffee jitters on top of the alcohol jitters. Eat a good meal.
