I did not wake up feeling any different. As a matter of fact, I did not wake up at all, the surgery was done under epidural, and I was awake the whole time. The epiphany came slowly over time as I started lowering the shield I had built up from being an incongruent woman who passed very well while knowing and feeling that something was very different.
As I did not have to protect a secret identity (and this is done subconsciouly), I started really interacting with the world as a woman, freely and without guilt. I am still learning everyday what it means to be a woman in various situations. And this happened because I no longer focused on physical transition. Before, I would stand back a little and think about the things that had to be done in my transition instead of being in the moment. Now, I am ready to open up, figuratively and literally.
