The most important thing is to make sure your getting plenty of water.I would suggest foods such as rice, simple soups, dry toast.Some fruits are easily digested when nauseous, maybe a banana or half of one. Nuts and seeds are good too, nutritious and easy to digest.My mother always made my father a poached egg when he felt sick, easy to eat and full of vitamins, minerals and protein.Hope you get better soon:-)

toast with rasberry jelly no butter or cheese, any kind of bread that absorbs the fluids, you are full of fluids and you need to get rid of the fluids so eat toast.
