Like Dena, I was full time for a significant amount of time before I had SRS (almost 3 years - not by choice, but due to a lack of money to pay for the SRS), so the gender dyshoria was pretty much gone before I had the surgery (it was probably gone shortly after I went full time in Dec. 2000), but the body/genital dysphoria? That was around bigtime until I had my SRS. Once I had SRS, it was immediately gone.
As for physical changes - well, not to a major amount of them post-SRS. You see, I'd been on HRT since 1999, and coupled with an Orchie in 2001, I'd already had major hormonally caused physical changes. It also helped that I seem to have a rather high amount of estrogen receptors (unlike many of us, I was never even close to being on the maximum allowable dosage of Estradiol or Premarin - I was never on more than half of that value), so that I had major breast growth before I'd had SRS (I remember my doctor asking me in 2002 when I'd had the implants, only to respond to him, "what implants?", which elicited the response from my doctor, that I'd had serious amounts of breast development). Over the years there has maybe been a little bit of extra breast growth, but nothing major.
