I have to agree with all the comments here in favor of the CPAP. My DH was a bear to live with because he was tired all the time. He knew he had sleep apnea but refused to get help for it. I finally demanded he go...or else!! Since he started using it and really getting sound sleep, his mood is much better, and our marriage is much happier!! The machine is very very quiet...I don't hear it at all.
