Now I alternate - one night with MAS, one night with APAP - so I don't go untreated. PAP is hell - I find It so uncomfortable and between struggling with the discomfort of the nasal pillows trying to crawl up my nose all night long (despite using the largest version), the constant awareness re hose management (I tend to to toss and turn) and having to re-adjust nasal pillows all night long because I feel like the air that's being vented is a leak, my sleep is severely disrupted because of this stupid machine. My AHIs were good for the first few months, but I no longer have access to a computer with a card slot so can't check my graphs anymore. What I saw then shows it's "working", but the accumulated lack of sleep makes my quality of life so poor that sometimes I just wish I could die in my sleep one night and not have to put up with it any more. I can barely work (have just taken a couple of months of leave without pay so lost big financially). I try to do things I used to enjoy and just can't get my brain or my body to function. It's not that I'm depressed or falling asleep in the daytime, its I feel physically and mentally exhausted. GP has tested me for all sorts of things and can't find anything else wrong.
One of these days I'm going to splurge on an oximeter because my fitbit is indicating on nights I use the MAS I might be experiencing low oxygen sats. I can see that low oxygen must be harmful, so I need to keep using the machine, but surely just wanting ONE good night's sleep after 5 months of being a "good girl" isn't too much to ask? I used to love going to sleep

I know there's not much point posting this here where everyone thinks PAP is the best thing since sliced bread, I just wish I could find a solution. Aaaargh! Thanks for hearing me folks. I don't need any replies, I just needed to vent.
Wishing good health and satisfying sleep to all!
