The only thing that really helped the ropey mucus and thick saliva was an over the counter mouthwash called BIOTENE. I'm sure you've heard of the product if you're going through treatment. It can be purchased at most drug stores and Target. IF your local drug store doesn't carry the product ask them to order it for you. For me personally, it was the only thing that really helped diminish the mucus and thick ropey saliva.
