Jamie, the mucous is just something that happens, drives you crazy, then stops. For me it was 21 days and it was gone. I wiped it out with Puffs brand tissues, which are the softest and strongest. I wish I had stock in them because I went through dozens of boxes. If you do a search, you will see that some people have had success with some cough preparation, I believe. I am sorry that I do not know the details of that. One last thing, I slept in an elevated position, and rolled up gauze to put in the "gutters" of my mouth. This absorbed the gunk long enough for me to get a little sleep. Tell her it WILL end.
