Hey Patricia - I do not have the problem to the degree that you have but I remember wrting the name of a med down that I had come across duing treatment that a pharmacist recommended for xerostomia - I wrote it down somewhere and will keep looking for it- apparently my organization skills during treatment was not so hot! Anyways, I wrote it down because I knew how much life would change without saliva - if I remember correctly, the med was described as an injection typically given during surgery which somehow served to improve dry mouth - I remember thinking that it seemed a little extreme at the time but thought I just might get to the point that I would be desperate enough to try it! I'm so sorry that you're having so much trouble - I'll keep looking for the name of the med - it may be a long shot - but something to check into at the very least!
