When I was down to 98lbs. (5'2"), I forced myself to eat. If I went into the kitchen, I grabbed something. A cracker, anytihing. And I drank alot of fluids. There were times that I couldn't keep anything down, but try to eat. Another thing, if you by chance get just a little bit hungry...EAT! Even if it's three in the morning! I remember many times laying in bed thinking I should be sleeping but feeling a little hungry. Especially when anxious, eating helps. Hot cocoa, ice cream, comfort food.
