Hi Dave,
Personally I think it's quite important to get testosterone levels checked post treatment. My surgery won't do this, but fortunately the hospital does.
In my case actually for a couple of months after finishing with hormone therapy, hot flushes actually became more erratic and worse, but eventually settled down and are now diminishing altogether.
It was around the 5 month mark post hormone therapy, that I began to notice more hair growth on arms and legs, less fatigue, and a return of libido.
