Here is the study I mentioned - the nadir O2 Sat of 66% is what has me concerned. It doesn't say it, but note that they came in and fiddled with the mask like, 6 or 8 times - no wonder there were "arousals". I use the same mask, and you can see (I think) my leaks aren't huge - but as I mentioned, I secure it with a chin strap too.
Another funny thing that is surely unrelated - but - in April of last year, I was staying over at my Brother's, and they had a super thick body pillow (I normally use one, but just a regular one). I had the best sleep in recent memory on those 2 nights (on my side with the pillow of course). I need to get one of those, but have not been able to find one that thick. Probably coincidence, but never know.
