Anyone using an "oral" mask?

[Airstream]

Mouth breathing will dry you out. No matter whether you have an oral mask or a full face mask.

I agree with archangle's statement for sure.
Also, I have an Oracle in my junk mask drawer with all the other masks that didn't work for me. I tried the Oracle, but kept blowing the clip right off my nose. After that happened a couple of times after I fell asleep, off to the junk drawer it went. My pressure is very high, so maybe that is part of the problem. I also agree that this mask business is like pulling the lever on a slot machine in Vegas.
