IT WORKS!!!
First of all I want to say I do like your Smart Nora and have tried everything I could find like the chin strap, the mouth piece and various other things.  The Smart Nora was working great and even my wife noticed the difference.  She even mentioned to me that there were a few times when she came to bed that it was so quiet she wasn't sure if I was alive!  ;-)
