I had a chin strap that worked well for that problem. If you google CPAP and chin strap, I'm sure you can find one. I had to add a strap around the back of my head to keep it from sliding forward, but after that, it worked great.

I have been using CPAP about 4 years and it has made a big difference in my life.

I use a RedMed Remstar CPAP with an Activa mask. This mask is far and away the best one I've ever used and I would recommend it.

This has not been an issue in the relationships I've been in. I wouldn't worry about it. If they do complain about it, just go one night without it and see if she likes the snoring better!
