Hi!
That is too bad about your throat problem! It must be terrible! I have a very sensitive throat and for years I was susceptible to sore throats constantly. However after I started using original Listerine after every meal, I have had no sore throats at all. It's very good about getting mucus out and getting the soreness to go away after only a few uses. Don't use the flavored Listerines. They don't work at all. Another thing I used before I found Listerine was to gargle with hot salt water. That worked pretty well but the Listerine was much better. I hope this helps.
