Denise,
I was similar to your husband when it came to coffee. Before cancer, I used to enjoy really good, fresh brewed coffee from certain kinds of beans. During radiation, and for awhile after, I couldn't tolerate any kind of coffee at all, and when I first began drinking it again, I couldn't distinguish "good" coffee from "bad". I knew I had finally turned the corner with my taste buds when I got to the point where I could tell the difference between French Roast and Kona (and the difference between fresh brewed and the stuff that had sat on the burner for a couple of hours)!.
