After MONTHS of frustration at not sleeping while wearing the mask, I had an appointment with my provider. I had been making myself keep the mask on my face for at least 4 hours a night. I had been told that Medicare requires this to continue paying for the use of the equipment so I made that my goal. I am somewhat ashamed that I had to get snarky with him to get my point across- but I am glad that I did. I am now on medication to sleep- so I get 5-6 hours. This is SO wonderful. I have not slept this long at a stretch since I was in my 20s. Yeah!!! For those having problems sleeping, etc, keep plugging along. Talk to your provider again and again and again. It took me several years but this is now tolerable.
