Congrats! I know how exciting it feels to take your first E pill, and you`ll never forget that time either!
I`v been on HRT for 18 months now, and the first thing I remember was needing to pee! it`s like if peeing was an Olympic event, I`d have taken home a medal! LOL
the worst part was middle of the night visits to the loo, but after about a month or so it calmed down a bit and now it`s either i`v gotten used to it or everything`s back to "normal" again.
I was on quite high doses of herbs before I switched over so starting on a low dose of E didn`t really change too much, although i do remember having the strangest cold shiver come over me after about 20 mins of taking my first pill, just came out of the blue, like the opposite of a Hot Flash.
beyond that it`s pretty much as the others have said above, though Most of the Physical changes (other than boobs, skin texture etc..) for me seemed to happen in the second year, Everything has gone curvy now even around my knees (Great for shaving now!), my toes have even padded out and I don`t have a visible shin bone ridge that runs down the front, it`s all quite rounded, facial softening happened mostly in the second year too, I`d describe it as dramatically Subtle.
breast growth has been slow and steady, no growth spurts or stoppages, just slow and gradual, i`m still a 36B as i was last year but they are fuller all around now and have less gap in the middle.
personality... that`s a hard one to quantify really, I`m more Authentic than before, and feel sooooo free now it`s unbelievable! but i`m only 2 weeks off from having lived full time as female for a year now, so i don`t how much is to do with that or continued HRT?
oh and for the record, i still have that "am i trans* enough..." thing going on occasionally, I`m not sure that ever really goes? it becomes Less, but i`v not shaken mine yet, so just keep taking your feM & M`s and hold on tight!
