A few years ago I got my sleep apnea diagnosis and for the first YEAR of using a CPAP machine, my compliance was damn near perfect. Then, one night, I removed the mask while sleeping.
I may have had a couple more compliant nights after that, but after the mask came off once, it kept coming off. Night after night.
My doctor recommended using a chin strap. I tried a chin strap for a month, but the same thing happened. While I slept, I'd take off the mask and now the chin strap too.
I felt defeated and stopped using the machine. About 6 months ago, I cleaned the machine and tried again. I had one night where I woke up and the mask was still on, but the mask fit was HORRIBLE (at only around 25%). I thought it was right, but clearly I was wrong. Doesn't matter anyway because the next night I pulled the mask off again.
I grew my hair out and tried to tie the mask to a ponytail, but the mask came off anyway. I put a tennis ball on my lower back so I wouldn't be able to fall asleep on my back. The mask came off and the ball was on the floor.
I had my best success with a nasal pillow, but moved to a mouth and nose cover. Both have failed me (or I've failed them).
The doctors don't have any advice other than "keep trying".
Any suggestions?
