Well, at least now I know, I'm not crazy! Since having started on the Advair Diskus, I have been having chronic dry mouth! I can't drink enough, to the point where I feel sick. At night, my mouth dries out, and I am constantly clearing the back of my throat which feels like it is covered in mucus. Which extends to not just my throat, but my nose and eyes. I've also been getting ear aches that are very painful, as well as jitters.
