Hello & Welcome Pieter
I have not had rad yet, but someone did mention something like you said. I'm sure they will respond.

I can see if they still sell it here and buy you some. Since you reuse the bottles 12 should last you a year, maybe?? I'll let you know.

Where did you recieve your radiation treatment? Because someone here (Mklein) is from Oregon and is to start rad on Tuesday. Let me know. I'll look at the store today.

Again Welcome. And congradulations on being cured.
Sincerely, Petey
