@ninalw, Glad to hear that your nephrologist is looking into this. It sounds like you are getting good care. I understand, now why you are concerned about the tacrolimus dosages. I have my hopes up that you will have some answers on your next visit.
It sounds like you are doing very well after the transplant. I am amazed at you playing golf already! As for me, I had a lot of reconditioning to do because I was dependent on a wheelchair and walker prior to my transplant. I was able to go to my son's wedding at 4 months post transplant, and to go on some hiking trails at 9 months.

Is tacrolimus your only immunosuppressive medication?
