Hi Suzanne. For the dry mouth symptoms, I found chewing xylitol-sweetened gum really helped - all the way through treatments. Trident was my brand of choice. It is habit-forming though, because I still chew it. Of course I still have a dry mouth, so....

Careful if you have a dog, though, because xylitol is poisonous to them.
At night you might try Xylimelts tabs. One of these between your cheek and gum lasts for a couple of hours of blessed relief and sleep. I get them on Amazon - haven't found another source.
