I'm at 4 3/4 years (started at 25) and I can honestly say I never expected how much HRT would change me. Even though the boobs are not fantastic (I'm barely pushing a near B), everything else has been great. Not just facial shape and smooth skin but I've gotten much more hippy like my mom and I don't gain much weight in my waist anymore. My hair texture went from good to awesome as well.
Put me in the "very happy" column 🙂
