The vaporizer works, but it will not do it all. You will still be waking up all night long with your mouth dry as a bone. You have to learn to sleep with your mouth closed. This took awhile for me. After about a year, things got a little better for me. My one functioning salivary gland kicked back in, and while not enough to keep my mouth wet, it helped. I used nasal decongestant sprays whenever I had a stuffy nose which made it easier to not mouth breath. Eventually things will settle down, but you will always wake up several times a night to drink and swish your mouth.
