I have been on Estradiol and Spironolactone for right around 5 months now. The only hair changes I have noted are that my facial hair grows a lot slower, my head hair is starting to fill back out, the chest and belly hair is mostly gone, and the leg hair grows slower. The other physical body changes.....I really don't see any, but my nipples fluctuate from uncomfortable to normal sensations and maybe a touch bigger but I think that is more wishful thinking than anything, and my Therapist says my skin looks softer. For mental/emotional things, I feel great most of the time now, when before it was normal for me to wake up and curse the fact that I woke up, I also no longer am driven to retreat into my female video game characters. I wish it would go faster, but am glad that it is going at the speed it is, as I still haven't worked up the courage to come out to my family.
Short version of the above: It will never happen as fast as you want it to, don't stress about it, good things are coming and the lovely people here are proof.
