Rolanda,
We all heal at different speeds. I was slow to heal myself. I could not swallow much more than water for months, and kept my feeding tube for another 10 months after radiation treatments ended. Like Larry, once I did start trying to eat, I had problems and I eventually discovered that my esophagus had a stricture, and that had to be dilated a couple of times.
Now, a little over 2 years since treatment ended, I feel great and have gained back my lost weight. I still have some swallowing difficulty, but I compensate by eating soups, milk shakes, and stuff that is easy for me to eat.
Please try and get your husband to be patient. I am by nature a very impatient person, but when it came to recovery, I truly took it one day at a time. Things do slowly improve.

Best of luck,
Danny G.
