I'm dizzy, light-headed, over-heated and just plain worn out after my workout this morning. Why? Because I overdid it.

I've been so focused on running from cancer by eating right and strenuously exercising -- research says it take five hours of vigorous exercise per week to keep breast cancer away -- that I drove myself to depletion this morning. It hit me when a wave of dizziness came over me in the midst of my outdoor workout. My body felt heavy, my strength disappeared, and it took every ounce of energy I could muster to put one foot in front of the other so I could get home. I suspect it was a combination of dehydration -- I didn't take water with me -- and heat -- it's really hot here in Florida -- and pushing myself too hard. The fact that I feel a bit under the weather didn't help either, I'm sure.

My body spoke to me today. And it's got my attention.

Just before my chemotherapy for breast cancer started -- when I was fantastically frightened by the toxic drugs that were about to drip into my veins -- I was told by doctors, nurses, survivors, friends that I would be just fine. I was young and strong and tough. I would easily tolerate the beating my body was about to take. This is what I was told and actually came to believe myself. I had no other choice really than to approach chemotherapy with a fighter mentality. And so I did. And I did pretty well for my first three doses of Adriamycin and Cytoxan -- given every two weeks instead of three in a dose-dense fashion -- followed by one injection of Neulasta 24 hours later to maintain normal blood counts. And then something happened. And I did not end up tolerating the chemotherapy my gut told me was a scary endeavor.
