necessary to wear full-face mask to alleviate dry mouth?

[springsteenfan75]

I've been having decent results with my Comfort Lite 2 mask (still not able to sleep through the whole night, but getting there). I was not labeled a mouth breather by the lab that conducted my sleep (where I slept for six hours with the Comfort Lite 2). However, my DME said that if I consistently wake up with a dry mouth, even getting a full night's rest with a non-full-face mask might not be enough. I've done a lot of research that seems to suggest there are many reasons one might wake up with a dry mouth (such as the very dry state of my apartment) that would not necessitate a full-face mask. I imagine reading the results from my Auto-PAP card would be the ultimate litmus test, right? Anyone have any thoughts on this matter?

Definitely reading your data (leak rate) would be the best way to confirm you have a leak problem. If you believe you are mouth breathing you can try taping your mouth shut (sounds crazy, but I ended up trying it and it does work - you get used to it). The blue painter's tape works very well; I believe it is 3M #3080, I use 2" width.

Others have suggested denture cream on the lips to seal them shut, I haven't tried that.
