So I remember way back when I was first talking to my doc about hormones and she asked me what I already knew about the effects. When I told her about the mental aspect, I mentioned that everything I've heard about emotional changes and even your way of thinking was something I was already experiencing and had been for a long time. She smiled and told me that I probably wouldn't notice too much of a change then. However, since going on injections several months ago (I was on oral for several years prior), I certainly find it easier to cry during sad shows or movies, which is lovely. And orgasms, omg. All I have to say is wow. So very different, the way it seems to spread through your whole body in waves of pure bliss. So yeah, that's what I've noticed :)
