jobeeg, I was there and know how awful that stuff is. I expect you will get some good answers about medications that help, because I have seen replies from others about that. In my case, I coped by rolling up gauze and putting it in the sides of my mouth to soak that stuff up so I could get a few hours of sleep. Puffs brand tissues are soft and strong for wiping it out of her mouth. Just today someone posted about the foam dental swabs that she used. I had forgotten those and have a whole bag of them that I didn't use because my mouth was too sore. I found the tissues worked better. Please tell your mother that it will end. When I got to the point where I was just about climbing the walls, I told myself at least it was just mucous, not pain, which kind of put it in perspective for me. There are many of us here who know just how she feels, and each one of us got through it and she will too. Good luck to both of you!
