Nancy, just an idea, but when your docs did their follow up blood work, did anyone check your thyroid function? Hypothyroidism from radiation is a common event after treatment, and one of it's primary symptoms is lack of energy. Many of us are on Synthroid from now till forever, and it works well with little in the way of side effects.
