Dry mouth - what causes it?

[KatieW]

I have pondered this too. viewtopic/t52758/viewtopic.php?f=1&t=52 ... ew#p480393

My leaks rate is usually zero or 1-2 l/m, and I have also taped to see if it made a difference, and it didn't.

After reading this thread, I turned my humidifier down....and this morning, had less dryness. I don't understand the mechanics of this, but I'm happy this worked. Will need to do a little tweaking, because I was a little congested, and I'm usually not, but this is a good avenue to explore.
