Pattie, I am a year and a half out on the chemo and radiation. Still on the feeding tube and am down to 86 pounds. I too have constant rip roaring burning in my mouth and more dry than I could ever explain. Wake up gagging as it is so dry I can not even move my tongue. Sounds like we are two in a million. Seeing my ENT next week and got my fingers crossed for some kind of relief. I'll sure let you know if he has any suggestions.
