I have a humidifier that I run constantly day and nite outside my bedroom door. If I forget to fill it daily, I awake with a mouth that is frozen in time. Like it was super glued. Get one and use it. You need humidity. Don't forget to use an Algae gurad to keep bacteria from growing. Buy the swimming pool algae guard as it comes in a gallon and is much cheaper. It is the same thing and the small bottles they sell. Some call it Bacteria Stat or whatever.
