See my post 18. If your doc will chart that you don’t tolerate CPAP well anymore (and just being sick of it and not using it are probably good enough), your insurance may cover it.
I’m basically happy with the CPAP but it is pain to travel with, I have the small portable one for road trips but it’s still a pain.
For use I used the same face mask thinking there was no difference between masks in terms of their effectiveness.
However, I switched from the full mask I had been using to a small mask the covers nothing but my nose, it has made a huge difference
