For about 2 years have been using DreamWear nasal pillow. It seems to fit quite well. I'm 5'10" 150#, clean shaven, and don't have unusual face or nose shape. Almost entirely side sleeper. Central (not obstructive) apnea. Heated climate line hose and high humidity setting. Typically wake up with extremely dry mouth
Early on in therapy I had mouth breathing and followed some forum suggestions here to train myself. And for last two nights since dr visit have returned to mouth taping with Somnifix - the first night this resulted in green happy face for leaks but not true the 2nd night - this was with brand new nasal pillow cushion. In using the built in mask leak test I suspect that as side sleeper that slight movements on pillow might be triggering leaks. ALSO sleep dr indicated to change nasal pillows @10 days as the soft material "breaks down/distorts" rapidly and the std @2 weeks is too long.
I have never tried a full face mask or hybrid, I am willing to explore that direction, and expect it might not be any more claustrophobic than nasal pillow with mouth taping. She also suggested a mask style such as Phillips: Wisp or Comfort Gel Blue.
I expect that I will go into supplier, get their input and in store try several options, but want to avail myself of the usually excellent experience and advice on forum - thank you.
I have a cervical cushion but find it triggers a bit of claustrophobia; have tried chin strap and am willing to try again (as needed), but found mouth taping to be easier, more acceptable, and generally effective.
