I thought a year, but did expect some major improvements by 6 months at least. This didn't happen. About six months in I told T that I just thought I would be further along. I always remember his reaction. He paused, glanced down at his notes, then slowly said, "Well, you have several thorny issues to work through."
I think that was one of only two times I cried in T.
So I'm going into year three now.
