I'm no expert on the matter, but I think that if you're on anti-androgens, or have had SRS, then they reduce the dose of estrogen anyway because it doesnt have to do battle with the testosterone before it starts working.
The general thing which I hear though is that more does not mean better and taking higher doses will not help matters, except you are developing PMS type symptoms.
I say again, I am not an expert. The best thing that could come out of me typing this is that I'm saving somebody more knowledgeable the bother of typing all this again
