This is an update from Mark, which we received a couple of month after recording this video testimonial:

I am continuing with the exercises and lifestyle changes that you taught to me.  I feel great and my wife says she does not hear me snore any more at night.  I still use the mouth tape, but I hope to reduce that dependency. My Positive Maximum Pause has settled to around 60 seconds with occasionally more if I am very calm and relaxed."
