I had one but never could sleep in it, and things got to the point where I was getting virtually no sleep and wake up in a panic feling like somebody was strangling me.

My Dr refered me to an orthodontist who fitted me with a mouthpiece that pulls my jaw slightly forward. Ever since I got it I have slept like a baby and wouldn't trade it fir anything. It is so much better for me not having the hose and everything that goes with a cpap, it isn't even funny.
