Muscles have Memory

Going into this 3rd week of radiation I am starting to feel the side effects of it. The fatigue is weird, it feels like something is not right in my head,like my equilibrium is off and my head is fuzzy. Fatigue is different than being tired.
I am still dealing with the neuropathy in my legs but I think I have learned to just live with it for now. When I am through with radiation I can see a naturalpathic doctor. Eric contacted one that he knows and he said it is best to wait because most Naturalpathic doctors use alot of antioxidants, while in radiation I was told to not use any antioxidants or vitamins. The way it was explained to me is that during radiation all of my cells are being zapped, the good and the bad, if I am feeding the good ones with antioxidants it will interfere with the radiation therapy.
Yesterday I started back at the gym, I took a cycling class. Tonight when I finished cylcing I could feel that my muscles were remembering my workouts a year ago. I am told that muscles have memory. As I cycled tonight I got a little teary eyed I hope I am able to continue through my radiation. The radiation techs told me to take it slow and not to over do it. That is so hard, all my cycling friends were there on the same bikes, in the front row. I got on that bike right next to all of them and had a hard time not taking off and pushing myself. I was cycling 2 classes a day, plus either a weight class or another cardio class usually two-two and half hours a day 6 days a week, as much as I want to be able to do all that again, I know it will take time and I have to listen to what my body is telling me. I promised my doctor I would stop if I get too tired and fatigued. I think he felt like he was tired of me asking "can I go back to the gym?" So for now I am taking it slow and trying to be grateful for what I CAN do, and not focusing on what I CANT do.
