Good morning, I relate to you knee comment. I had my left knee replaced a few years ago and am beginning to feel pain off and on in my right knee. I do NOT want another knee surgery. Uff da. Yes, getting the weight off IS the answer and we CAN do this. It has taken me forever to get myself motivated. I am motivated at this moment and I'll call that good. One hour at a time sometimes. We didn't get this way overnight. It will take time but most of all it takes perseverence. Good luck to you.
