Can't say I know much about it, but I would say the radiation is working well. Sounds like it hit the bullseye.
If I were you, (and I am not), I would give my body a little rest and see what happens. I have not seen any studies that say that beginning ADT sooner or later is significant in effectiveness.
But that is why you have experienced and professional doctors advising you.
Good luck, and conbgrats on the early success.
