I'm a very active sleeper and use the P10 pillows, however I would knock these loose most nights.
I also started mouth breathing so things were not going well for a while. But I invested in a chin strap which I wear over the P10 straps, and I no longer mouth breathe, but just as importantly it keeps the nasal pillows in place, no matter how much I move around.
This combination has really solved the problem for me, and I would recommend it to anyone with similar problems.
Failure is NOT an option.
I am looking at getting a new mask as part of my APAP package. When nasal pillows first came out, I tried them. I can't recall which brand, however in the DME's office they were fine. When I went home and tried to sleep the air pressure was so uncomfortable it was ridiculous. Not only did my nose feel like it would explode but my nose was very dry. I also had issues with leaks due to different sized nostrils.
Since it's been about 7 years, has the technology changed much to address my previous issues?
