Hubby has sleep apnea and uses the CPAP. He has to make sure that he is clean-shaven or the mask will leak but I don't think you will have that problem, lol.
When he forgets to put it on he snores and then I poke him to put it on. He sleeps better with it and is more rested (better oxygen distribution). To me it sounds like white noise and it actually helps me fall asleep easier.
