I'm on day 8 of IMRT and have had 3 Erbitux treatments for tongue cancer. I have daily nausea (both doctors think it is my PEG tube because if I open it and release some fluid, I feel better) but a good appetite. The last 2 days I have not been able to stand the taste in my mouth. Even water is disgusting to me. Sugarless gum is OK for a while. Sugarless candy makes my saliva too thick. I want to keep hydrated and swallowing without getting nauseaous. Any suggestions?
