My ESSC was caught before it escaped my esophagus, but it had ALMOST closed my esophagus, to the point no local GE doc could get an endoscope down past the tumor, which was almost circumferential, with a tiny hole in the middle. I was having problems with spasms, which would close my throat entirely, at which time, I'd develop the hypersalivation problem. I've lost up to 16 oz of saliva and stayed up almost all night to avoid aspiration, until a spasm eased. I've tried every drug they could think of except Botulin shots, which have their own problems. My cancer is in remission, but I traded scar tissue for tumor, so I still had my stricture. After two dilations, with another, at least, to go, the spasms don't close my throat entirely. However, the drug which seemed to help the most was glycopyrrolate, which can be crushed and given via a feeding tube. It is not without its side effects, a mouth as dry as cotton, constipation and blurred vision. It can't be given intermittently; it must be daily. It's given most frequently to Parkinson's and CP patients, who have the same problem. You might at least ask about it...
