My 9 year old daughter has had Mono for 5 weeks now. Her one and only complaint is nausea. She wakes up with it and goes to bed with it. Her diet consists of 2 pieces of toast in the morning, won-ton soup for lunch, boiled chicken and applesauce for dinner. If she even takes a bite of something not as bland as what she usually eats, she's in bed with terrible queasiness. I have her taking Vitamin C (ascorbic acid form), and a little coconut oil on her toast. Her doctor prescribed 6 pills of Zofran to help with the nausea that I will start to give her in the morning. Has anyone else had this kind of nausea and a bad fullness feeling? She says she feels like her stomach is twice it's size. If so, how long did it last? Thanks for any advice.
