rwarm, I think it will be safe to stop the ethyol because with IMRT, he will most likely regain some saliva function after treatment ends. I had IMRT 4 years ago and they said I didn't need to have the ethyol. They were correct and I can spit with the best of 'em. Not having to go through that should pick his spirits up considerably. Please tell him that most of the many, many people on this forum have survived radiation and gone on to live happy, normal lives. He can do it too! We are all pulling for both of you.
