@delilahrose I have dry mouth once in awhile also. What helps me is Biotene mouthwash - https://www.biotene.com/dry-mouth-products/mouthwash/. I think you can get it at most drug stores or supermarkets as well as online through Amazon. The inside of my nose also gets dry and I use a petroleum free CPAP moisturizer like this one - https://www.amazon.com/RespLabs-CPAP-Chap-Face-Cream/dp/B01IOE876W/ref=sr_1_3. It also seems to make breathing through my nose a little easier.
