One thing I can definitively tell you about being off the estrogen part of my HRT is I feel my old testosterone feelings creeping back in. It is not a good feeling.
Early in the process I was what I called weepy, now I am "trending" towards much of my old aggressive self.
The only positive I can see is, as I have written extensive about here in Cyrsti's Condo, there is a chance I will be allowed to go back on my estrogen in the future.
At that point, I can start the process all over again.
