Ref. Sleep Abpnia. Have just come back for checking after the first week. Down from 67 times an hour to 17. 67 was considered extremely critical and 17 is considered moderate. When I was asked if I still snored I said I don't know as have been relegated to another bedroom, as the wife refuses to sleep with a spaceman. I have another contraption now to hold the jaw in place to stop the escape of air. There must be others on site who have this sleep problem, did anyone get rid of it completely, or is this another aid to add to all the rest for ever. Cheers John Sabourn
