Joann, one suggestion I haven't seen here is to try Megestrol for appetite stimulation. Here's a link:

It helped my father when he had no appetite years ago, and is now very effectively helping my landlady with same during her chemo for breast cancer.

All the other thoughts our friends have added are good ones. I had swallowing problems too, for months, and had the tests, speech therapy, throat dilations, etc. Eventually things returned to more or less normal.

My thoughts are with you and your husband.
