Stephanie, I really know how Phil feels, my mouth is always dry because I haven't been able to drink anything even sips for months. I agree with Nancy, I also have a small spray bottle filled with water that I use to wet my mouth. I was given a small bottle of moisturizer spray called Toothelle made by Sage Products Inc that works well and I like better than Mouthkote.
I am also spending a lot of time n my room with the humidifier going as our house air is very dry in the winter. Sitting here watching the CFL Grey Cup game and holding my lips closed with my fingers so I breathe through my nose, silly but it helps dry mouth.
