It took me some time to get used to my machine, or rather the mask part of it. they actually gave me the wrong one to start with. I tried a couple out in the hospital in overnight stays & some how they made the mistake of giving me the one that I hated. I eventually bought one that swivels so that it gives you more freedom of movement. I can actually sleep on my tummy, which I am doing at the moment so that I can have a heat pack under my pelvis which relieves some of the discomfort from bladder & bowel problems.
I have found that the humidifier helps a lot & a cover over the hose from it to the mask helps keep the air warm in winter.
I don't know about the REM sleep, but they found when I did the tests that I stopped breathing for up to 38 seconds at a time, many times during the night.
I find that I sleep much better & feel more alert the next day after I started using it. There have been times when the big D is prevalent that it stays off, but mostly I just undo the hose & leave the mask on when the loo beckons, much quicker. Reckon that if a burgular broke in he would get the daylights frightened out of him if he ran into me.
Love
