Anne:
Gordon will be fine, just stick by him (As I'm sure you plan on). Everyone has said how it takes time so I won't elaborate. It all varies so widely. Almost 4 years out and I still feel tired on some days, some food has no taste, the whole saliva issue, etc., etc. But I have come to realize that I can visit my wife everyday, see my lovely Kids and Grandkids, and I'm on the green side of the grass. It takes some longer than others to figure all this out. There is a "new Normal" out there so stick with him and you both will continue to grow.
