Hi I’m new to this forum, but not to CPAP therapy, I’ve been doing that about 12 years. I have a Resmed S11 with a zest nasal mask. I have been using the myAir App and it says I only have maybe .01 or .03 events at night, which is good, and my mask seal is good. Lately I have been sleeping more than 8 hours and not feeling completely rested. I have dreams so I know I am sleeping. I have always been a light sleeper and it seems the only time I really get a deep sleep is if I take a sleeping pill (usually zzzquil or unisom). My pressure is at 8 and I think it’s fine, because I do sleep well on a sleeping pill. Anybody else have issues with sleeping deeply, and is there anything that worked for you?
