Are you saying that you refused the 18 months of HT after your salvage radiation and you didn't even have it before and during the radiation? If so, you certainly have strong convictions about
quality of life.
To answer your question... No, your PSA will not go down on its own, but will continue to rise as the cancer progresses, which I hope will be slowly.
The latest (just presented this week at the ASCO meeting) data shows that there is no disadvantage to waiting to start HT until symptoms begin to develop or scans show progression.

Here's the study:Immediate versus deferred initiation of androgen deprivation therapy in prostate cancer patients with PSA-only relapse.
This was an analysis of a database of men who had a recurrence after surgery or radiation. I don't know if it applies after salvage radiation. It's not proof, which can only be inferred from a randomized controlled trial (one is under way), but it is eye-
