Dry mouth all of a sudden - pressure?

[Superatomic]

I've been using the dreamstation for  year and a half.
All of a sudden the past couple weeks i've been experiencing bad dry mouth even with high humidity settings.
The water is definitely going down as I check every day.
I'm thinking since I have lost almost 50 pounds that the pressure needs to be lowered from what it was.
Perhaps there is now too much airflow and it will dry the water no matter what?

Does that make sense as a resolution?
Not a mouth breather.

Dry mouth is often linked with breathing through your mouth rather than the pressure check for leaks, a chinstrap or soft cervical collar my help reduce the mouth breathing
