I saw the thread. I haven't posted there, yet.
Sorry about your knees. For me, though, it was more severe. I've got hereditary hemochromatosis which, combined with fatty liver syndrome (from being overweight for so many years) has given me non-alcoholic cirrhosis. Basically, I'm half way to liver cancer. The treatment for HH is pretty gruesome (weekly bloodlettings) but it's much preferable to dieting, IMO. I have to do both. I should weigh about 100 pounds less than I do (98, specifically), so there's my goal. Fortunately, there's no deadline (other than death) so falling off occasionally isn't as guilt inspiring as it used to be. I just have to get right back up on that horse.
Which I will do, so help me.
