I am a 46 year old male and have sleep apnea. I use a CPAP with a high setting (15). I have a mask that covers nose only because the full face mask was a bit claustrophobic. I have noticed that I am waking in the middle of the night and morning with a mouth that is so dry I cannot swallow...teeth and tongue really dry. I am definitely still mouth breathing, even with the CPAP. I also noticed over the last week that my tongue is yellowish (related?). I wake and really do not feel refreshed, like the CPAP is not really helping. I also have acid reflux, which compounds the problems.
What can I do? Any suggestions? Has the yellow tongue thing happened to anyone else?
