Just discovered this site and forum. For 15 years my wife has said I snore and stop breathing every night, but a sleep study a few yrs ago was inconclusive. Seven weeks ago our cat woke me early in the AM for food, I went back to bed planning to get up when alarm went off in 30 minutes. I had a bad seizure (never had one before), dislocated my shoulder and fell out of bed on the already injured shoulder at the same time. After EEG and MRI tests (both negative) in the following week, no one has come up with a reason for the seizure, but my family Dr suggested sleep apnea as a possibility. Right away I started sleeping with my wife's oxygen concentrator in case that was it. I took a home sleep test and sure enough, it confirmed what my wife has said. I got fitted with a ResMed AirSense 10 two weeks ago and have been using it every night. I'm not sure I sleep better yet, the pressure may be waking me up a few times a night, but my wife says NO MORE SNORING ! I'm afraid to NOT use it in case apnea was the cause of the seizure, the dislocated shoulder was/is very painful.
