I was in my 50's when all of a sudden my body started producing lots of saliva, non-stop. I use the term "my body" because it felt like something else that was turning against me. Why was it doing this after all these years? It wasn't necessary, so why make my life completely miserable.
This sounds like such a small problem - especially compared to horror stories of major illnesses that you hear about other people going through. But once it happens to you, you realize that your mouth constantly - and I mean constantly - filling up with lots of saliva is an awful, life-changing event.
I saw several doctors about this - both primary care and specialists. I took several kinds of antihistamines, in both pill and nasal-spray form. I went in for allergy shots for months. I bought plastic covers for my mattress and box spring (dust mites). I stopped eating everything new I could think of that I didn't use to eat; stopped them one at a time for weeks at a time in the hopes of zeroing in on the culprit. I took several kinds of heartburn medication. Even had a barium swallow and x-rays to see if there was a problem with a deviated septum.
These attempts took years... and none of them worked. I thought I was destined to spend the rest of my life just swallowing constantly or else gurgling when I talked. And I was devestated about this.
From time to time I would Google "excessive salivation" to see if anything was new. One of those tries mentioned Sal-Tropine. I'm pretty sure I had seen this before, but this was new so I made an appointment with my doctor and he gave me a prescription.
And that afternoon - that very same afternoon - it worked! (This was unlike many, if not all, of the other treatments, where I always had to wait weeks for results. (That never came.) When I saw my doctor about this he explained that it was also given to patients about to receive anesthesia to prevent them from salivating while they were under.
He said that for some reason my body was stuck in some kind of groove where it just produced massive amounts of saliva, and that the trick was to get it back to its old groove by stopping this production for an extended period of time. So I took the pills for a few (3 or 4) months, and when I stopped - lo and behold - my body didn't go back to its old, betraying ways. After several years of constantly producing tons of saliva, I am now back to my old, normal ways.
Hopefully this post will help others. Even if Sal-Tropine doesn't work for you, the point is to keep trying until you find something that does so you can jerk your body out of its bad ways and back into its normal ones. Good luck!
