I have a 16 yr old daughter that is constantly suffering from nausea. She is not pregnant. She does have a heavy study load in school, taking highest track honors classes and is adamant about making good grades. For the record, I do not pressure her for the grades- she is allowed to work at her own pace. Crackers in the morning seem to help a little but she still isn't able to eat at all in the a.m. and not much during the day. I'm concerned that she may be developing an ulcer from worrying about her grades too much.
