Gilda, I am not even on narcotic medication. I am on Tramadol and that is I think if I understand it, a drug that mimics some narcotics, but it is not that strong as the doc said I can drive while on it and I only take two in the morning and two in the afternoon. I had trained pretty hard before my LTKR, it was part of my weight loss regime after my hip replacement last Dec. I was up to doing a 5 mile walking DVD 5 days a week before my surgery and it helped me lose 70 pounds. I was so hoping that I would "fly" after my surgery, but the knee not bending has held me back some. But energy wise I am back to normal and no, no "extra" medications are being taken...LOL
