Hi, Kerri
The combination of irradiated tissue, fungus and dry mouth is not a happy one. Have you asked the doctors if it would be ok for you to try one of the moisturing gels at night?  Also - are you mouth breathing at night? Would one of those nasel strip things make if easier to breath through you nose?
