I started HRT 4 years ago under, Informed Consent. Initially I had no idea what to expect for the psychological changes it might have. I figured that Id stick my toe in the water so to speak and at worst if I didnt like the effects, Id simply stop. But as it turned out I LOVED what it did for me. The next step is if you decide to add, Progesterone too. For me it helped w/ breast development. But its effecticveness can vary; Some Gurls swear by it, some swear at it,. In my own case, I suspect that its partly responsable for turning me, Straight(hot for guys). It can also make you a bit, "baby cazy"(wanting to get pregnant). YMMV,,.
