Hi CJ, I forget, does your husband have a peg? I have found that the excess saliva and throat goo is worst after I try to eat and drink using my mouth. That is the main reason that I have pretty much stopped eating now, I still can force a little down but then I spend 10 minutes in the bathroom suctioning and washing so it isn't worth it. I hope that he can avoid the gagging/choking because it itself can cause stress and is a vicious cycle.
He should go fishing if he can, I went hunting yesterday and although it was tiring it is also good to get out and get some fresh air and a little exercise. And to take you mind somewhere else too.
