My OSA is caused by my tounge being to big. I can only wear that thing 4 hrs, but I sure as hell feel a lot better in the morning
It took me 4 years to find a mask I could actually sleep in and told my Dr. 2 years ago that if he didnt lower my pressure 2 or 3 inches and try to work with me on it I was gonna go find one that would. I had to use O-2 for 6 months because I was just about dead.
