I was instructed to use ONLY distilled water. Any other water will have minerals and leaves a residue at the bottom of the tank even after dumping it daily.

Just a few weeks ago I've started to experience dry mouth. I wake with the insides of my mouth stuck together. Anyone have similar problems, and how did you deal with it?

Just recently I was made aware of glass distilled water. Has anyone knowledge of what is glass distilled water and how does one make it? All comments will be appreciated.
