Dry mouth? OK. That could be our nice wee friend, Sjogren's Syndrome. Dry mouth, and dry eyes, and dry lungs, and dry...oh well... !
Sipping warm water is good. Keep hydrated. There is a mouth spray you can use, Artisial. Tastes foul and I think a sip of water is better!
IF dry eyes, artificial tears, preservative FREE, There is also Dacudoses, an eye wash and for night time LacriLube - an ointment. These are all pretty good for dry eyes.
I have posted quite a bit here in the past on gastric problems and our jolly little friend *regurgitation...such a nice bedfellow... Put in a search.
Take care -
