Sounds like really bad health OCD and I'm glad he is getting some medication. There's no way to just stop what he is doing (the swallowing tests, etc) on his own. What happens is his anxiety builds to a level that he just HAS to test. Then he'll do a cheerio test and it will relax him for about 10 minutes, then he'll start thinking,"Maybe I didn't do it right that time" maybe this, maybe that... anxiety builds to an uncomfortable level again and he has to do it again to take that anxiety away, and it goes on and on. I know, I've been there (not with ALS or swallowing, but the checking and checking and checking until I thought I was going to go out of my mind) You have no idea how bad I feel for your husband, I am almost in tears because he is locked in a living he// You are one special wife to help him so much and not get frustrated and angry with him.
