Nanny, use Puffs brand tissues to wipe out your mouth. Softer and stronger than other brands. Wish I had stock in them! Also, to sleep while that wallpaper paste was pumping out of my mouth, I rolled up gauze and put it in the "gutters" of my mouth. That absorbed the gunk for a couple of hours, letting me sleep. In my case, the stuff stopped after exactly 21 days. Don't know if that is more or less than others. Please know that it WILL stop. This is one of those small prices we pay for being alive.
