If anyone figures of the dry mouth issue, please let me know. I wake up serval times per night with extreme dry mouth. It feels like someone filled my mouth with sand..lol. This can't be good. I found something on line called Ora coat. Has anyone tried it? It attaches to your teeth or tooth and is suppose to keep your mouth from drying out. Not sure how it works. I would think a mist in the mask would be good but I don't think they make one.
