Danny, I know what you are going through, having so recently been there myself. I never heard about Robitussin, but I hope it works. In any event, even though I felt the wall paper paste I was producing would never end, it did and yours will too. I have found that the Puffs brand of tissues is stronger than Kleenex for clearing the stuff out of your month, for what it is worth. Wish I had stock in it for the amount I used... Hang in there and KNOW that this too shall pass.
