My daughter has had Mono for 8 weeks and her only complaint is the nausea. She can only eat about 5 foods -- boiled chicken and cooked peas as an example. We took her to a Gastroenterologist who said that Mono picks and chooses which organ(s) it wants to attack. For my daughter, it seems to be her digestive tract. They said there is nothing they can do for her; she'll just have to let it run its course. The nausea is frustrating because you can't eat the foods you want anymore. Let me tell ya, my daughter is sick of peas and chicken! I wish I could tell you of things that helped my daughter, but after 8 weeks, she's still not much better. Sorry. Hang in there!
