Sean -

I would imagine that the after treatment issues vary in type and intensity for anyone whose gone through the surgeries and radiation / chemo treatments.

Fatigue is part of what I'm dealing with, among other things. My thyroid seems to be the cause of at least part of the dragging / sleepy feeling. (I'm about three years out from my most recent set of surgeries and radiation treatments.)

The responses above were pretty comprehensive regarding information available and what to do about fighting fatigue.

I push through the fatigue as much as I can and try to get as much restful sleep as possible. It may be annoying, but it's your new "normal".

Good Luck
