Actually, I find I have become somewhat mellow. I don't get as angry as I used to, but I express my emotions more readily, for instance I cry more easily now and when I get really pissed off I don't hold it in, although I'm more vocal and less physical. I think you still have some brain effect from T because you say you are using spiro, which blocks uptake. I'm on suprefact which actually supresses the production of T. I can't talk about the difference between P and No-P because my endo put me on micronized P from day 1 (and micronized E as well).
