Pete, be careful about putting the DPS surgery off too long; depending on your progression you risk missing your window.
I'm sorry that your wife is having such a hard time accepting the realities of this disease. It must make things so much harder for you. I worry that she won't be prepared for the rest of this journey. I feel so badly when I see comments about doctors not offering help during clinic appointments. We always get good information and helpful advice. I can see, though, how unhelpful that would seem if I were expecting them to cure my darling.
Finally--loser? No, I think not. I offer as evidence that the wife you adore loves you, and so do we.
