Amy, I am three years out from that time, but I remember just not bothering with real food when everything started to taste "wrong" and then a little later like cardboard. Generally, salty things tasted okay the longest. I ate quite a bit of smoked salmon the week before I lost all taste. Tell your husband that PEG is going to be his new girlfriend for a while, and having her to get drugs and food and water into him when his mouth is too sore is honestly a lifesaver. As far as the canned food for the tube, going directly into the stomach means there is no taste to dislike, so that shouldn't be a problem. My best wishes to both of you. Please, while you are dealing with the now, do not forget the long view, and know that this is a very small piece out of what will, with good treatment and luck, be a very long life.
