I ended up trying PM for two days, together with SP the first day. The physical effects I noticed were that shortly after taking a pill, my nipples would go erect and become sensitive, staying that way for several hours until I guess the body had processed most of the PM. My skin became freakishly smooth, and stayed that way even for several days after I stopped taking PM. I also noticed some fat redistribution in my breast and stomach area. It seems pretty amazing it can have such a fast effect, so maybe my mind was playing tricks on me to some extent.
On the negative side, I felt physically weaker, you know that feeling when you are on the verge of getting a cold but it hasn't yet begun. This went away pretty soon after I stopped taking PM. Not pleasant at all and makes me reluctant to go on PM for a longer amount of time.
While it was exciting to do something with the potential to feminize my body, I also started feeling scared of the masculine me fading away, so to say. After I stopped, I felt that 'ok, this may not be for me at this point in my life at least' and was happy I'd tried something and was that one experience richer. But now, a month later, I am confused again, having strong urges to go back on the PM and take it a step further this time around. At the same time, I like my male body and don't want to mess it up. I wish there was a way to instantly go back and forth between male and female! It's really confusing, and I'm having a hard time distinguishing what is unhealthy obsession from what is a real part of my identity.
Right now, I want to figure out how much is hormone based, because for me gender dysphoria comes in cycles, and I figure it's got to be related to something biological happening, otherwise how can it hardly bother me at all for extended periods of time, and then come back with a vengence. So I'm doing blood work to see if anything is up. And I might go the opposite way for a while, attempting to boost testosterone to see how that affects things.
