Our ENT (who had coventional XRT over 15 years ago) said her salivary function continued to improve for a number of years after treatment -- as I recall, 5 or so -- she also now uses Evoxac which she prescribes for all her xerostomia patients as well. She says it helps a lot, especially at night when she still has dry mouth issues. (She doesn't have much problem during the day but does sip water).

p.s. Barry has been doing his swallowig exercises religiously and even after just two weeks is having far fewer problems, maybe due just to healing -- and loss of inflammation -- and some to the exercises.
