Within a week. I felt much happier, and more accepting of myself. At first it was an undefinable feeling, then it hit me - it was the absence of dysphoria! Having lived decades with self-loathing and shame, I had forgotten what it was like to be okay with myself. It was a nice feeling. Not that everything has been all hearts and flowers since then, but I know now I can never go back to being male and be happy.
