First of all, thank you very much, Sammie, flame, Eve, Kari, Pansy-Mae, spanky, Clara, and Karren, for all of your kind replies! They were a great encouragement to me, and lifted my spirits significantly. You are wonderful and very supportive!
I may try to do individual replies later, but I wanted to at least post a general reply.
I think that indeed what I was observing was an effect of the PM, as many suspected. After reading these, I realized that I had essentially increased my dose about a week ago, from 500 - 1000 mg/day to 1000 - 1500 mg/day. That was the result of the combination of two things. One was that one of the mental effects that it produces is lessening anxiety in general, particularly social anxiety; so I figured instead of taking a dose at bedtime, take one during the day (when I have anxiety

). To do this, I brought some from home with me each day. On top of that, things were somewhat stressful last week, so I took an additional dose before heading home, so I wouldn't be as edgy when I got there. So, around the time I increased my dose is when I noticed the feminine persona disappear. Coincidence?
So, I'm pretty sure you have the correct diagnosis, if you will: it turns out that what was concerning me was what I've been trying to accomplish, I just didn't know it would "look like that". Sorry about that!
So, even with my false alarm, and being something of an outlier on several counts (not trying to grow breasts, having what appears to be a minor case of GID), you'll still keep me, eh? Thanks!
Hugs
Michelle
