Thoughts on this breathing pattern?

[Madcat207]

I don't see the flow limitations like I thought I would. I'm thinking a small mouth leak that slowly grows and the recovery spike is you waking up from it.

I could totally see that.  I have been fighting mouth leaks my entire time, and still fight it.  I have a chin strap that somewhat works, but I still catch it happening (and I can still wake with a dry mouth at times).

Madcat, if this is a persistent and intractable problem, the mouth leakage, you might think about covering your lips with tape as I do.  This seems dreadful, and many here look with askance on the very idea...understandably.  However, taping is what I must do if I am to derive any benefit from my device and its proffered therapy.

If you have already considered it and discarded the idea, that's fine and I won't pursue it further here.  If you'd like more information, I would be happy to relate my experience to you.
