Ginger has long been used to treat nausea and seasickness. And, since having a hangover is much like being seasick, this easy remedy works wonders. If you're really green, the best bet is to drink ginger ale (no preparation required). If you can remain vertical for 10 minutes, brew some ginger tea. Cut 10 to 12 slices of fresh ginger root and combine with 4 cups water. Boil for 10 minutes. Strain and add the juice of one orange, the juice of half a lemon, and 1/2 cup honey. Drink to your relief.
