Sorry to hear of your husband's setback. It seems he has been struggling since he was diagnosed. I do hope and pray he can get some relief and start eating and put some weight back on so he can be strong enough to fight this disease. My husband has never had radiation so cannot help you with any ideas, but my thoughts are with you. Keep staying strong for your husband and make him smile. I honestly think a positive attitude helps, but yes I know it is hard to be positive sometimes when they are going thru so much. Also, try to get some rest yourself.
