Betty, There are anti-nausea drugs out there your doctor can prescribe. I tried a couple different ones before I stayed with Zofran. It helped, but with that and the pain med. it caused constipation. I can't help with the feeding tube since I didn't have one. I ate soft foods, chicken soup, drank nutritional drinks, etc. There are other forums on here where people have listed different eating ideas. I'm sure someone else out there can help you more. Take care.
