Glad to hear the Clonidine is working for him.
During my two years of ADT3 I had few and mild hot flashes. I dunno the reason for that for sure (some guys are just lucky with their symptoms) but I suspect that it might have been the fluoxitine (generic Prozac) that I took for my depression. As well as its use as an antidepressant fluoxitine also used (at lower doses) for hot flashes.
Not sure if I recommend it, though. The drug has sexual side effects that manage to be annoying even for men on hormones. See my thread: ADT4 - Prozac Giveth and Prozac Taketh Away
