I find that sometimes when I climb into bed, those cold covers make my nose want to stop up. What works for me is to pull the covers up over my head and breath under the covers for a few minutes. The warm air reopens both nostrils and warms up those cold sheets. Then I can come out from under the covers and go to sleep normally.

I don't think I open my mouth while sleeping but apparently I have started drooling during sleep. Many a time I wake up and the the pillow case next to my mouth is wet. I never drooled before treatment.

Lastly, I seem to have lots of sinus drainage that dries in my throat during the night. I wake up every morning feeling like my throat is coated in dried glue. Warm water gargles loosen it up and then it's a bunch of hacking and spitting to clear all that gunk. During the day it seems I have a lot of very sticky rope mucous, hard to clear out. Fortuntely my throat is not burned up from radiation so it doesn't hurt to hack.

Oh well, life goes on.
