When I have a mild stomach ache and nausea, I try to make it feel better by eating a meal. As long as my stomach is full of food, the nausea goes away. Some of my friends say they can't eat anything when they feel sick but I feel like I HAVE to eat or I'll be dealing with tummy pain and wooziness. When I feel sick I have to eat something substantial about every 90 minutes. Is this even remotely normal? I've been to the doctor and she said there is nothing medically wrong with me.
