Well..

Radiation treatments three different times, see attached clinical history.

Each treatment (69 total...) was done by the same radiologist.

I drove myself to and from each treatment.

During the last one, SBRT, my wife asked my radiologist "shouldn't I be coming to his radiation treatments to drive...!?" My radiologist's smiled, her response, "Kevin, no, he's fine...!"

Then again, during SRT I drank regular coffee and still had a Manhattan or two to close out the evening...

As others have indicated, your biggest challenge in driving to your appointments may be bladder management!

Study of one...
