Dear john1016,
I underwent 43 radiation treatments and experienced no nausea. None. My treatment was different, but none of the guys I knew were nauseated. I'd call the doc.
My best to you in your struggle.
Bill
Dear John1016, I am presently on day 15 of radiation treatment, no nausea, throwing up, they are only targeting the prostate bed in my case, but I think you should consult the doc.
Regards Mal.
