This may vary but in my case it was as though a veil was lifted. I moved from blacks and grey to technicolor, from mono sound to full surround sound, from being sensorily limited to fully sensate (more empathetic/connected, improved sense of touch and smell, even colour looked more vibrant). In short, I felt more present, a little more emotional, but as I stayed on low dose after my head became a little fluffy I have not experienced the significant emotional or mood swings that others sometimes describe. The above is why I take hrt. And of course, no more dysphoria. It really has been miraculous. If you are ok with, or welcome the physical changes, then if you are trans it really is the elixir of choice!
Safe travels
