I had the same problem. It helped me to ensure I got all my fluids in because I was constantly drinking trying to get rid of it. I think it was just a way my body reacted to the change. It went away for me about 2 1/2 week post op. At this time I was able to get all my fluids in so I think that helped to get rid of the constant cotton mouth. I say just drink as often as possible, I also brushed my teeth several times a day to try to get rid of it.

Could it possible be your body ridding itself of yeast? I know on sugary/carb filled diets (my current diet) the body can get systemic yeast infections. When that changes it can go through detox. Whenever I take antibiotics I ask for a script for diflucan because I inevitably suffer a yeast infection of some kind. And I am sure you were pumped full of antibiotics during surgery. But of course, I am not a doctor. I pray your hairy tongue/throat gets better quick!!

I had the same feeling and it turned out that my uvula was a little traumatized during surgery. In order for it to heal, it had to shed a layer of mucous that seemed to take forever!!! I think it was finally gone after about 10 days.

I had the same feeling! drove me crazy, I am 8 days out and it has gotten better so give or take I say about 10 days.
