Garlic and Pertsovka with honey. Hrenovuha also works fine.
P.S. As a comment to the post above. DO NOT FORCE YOURSELF TO EAT. The digestion process takes a lot of your energy. Don't waste it when you feel bad. Don't worry you won't die w/o food if you won't eat for a couple of days or a week. Drink chicken bouillon if you feel hungry.
