I've had a CPAP since 2010, I hated it at first and didn't use it like I should. For the past year I have been using the pillow mask, it took awhile but I used it every night. Last week my machine broke and it has been miserable, waking up all thru the night, tired all day, forgetful and crabby. Going to pick up my new cpap in an hour and I can't wait. Never thought I'd be saying that. Anyway use it every night, you will get use to it. Down the road after surgery hopefully you won't need it. Good luck!
