this sounds normal to me as well. Once you are done with the radiation you do not have the constant interaction with your medical team. Also one feels worse after the end of the radiation treatment.... Eating is frustrating even when the taste begins to come back. Things do not taste right and some things definitely turn you off such as red meat (in my case). I have eaten a lot of yoghurt (many different flavors). Things are happening when the mouth is healing there are many changes. There are blisters, irritations and color changes. All of this can be unnerving. Prior to being diagnosed with cancer, a blister or ulcer is not a big deal, now however it is far more sinister. (even if you know damn well that it is nothing to worry about it still rattles your cage).
If your husband is working out after 6 weeks he is doing fine!
