I have thought of using a humidifier but have not tried it yet. My mouth was so dry every night that I could not sleep until I bought some Biotene Oral Gel. Now, I put a little bit on my tongue and it allows me to sleep. I usually get up a couple of times during the night and I use it again. It is at least good for a few hours.
After reading your posts I guess that I should no longer complain that I live in one of the most humid areas of the country.
