@tlt, I have come across this link titled, 6 things to tell your anesthesiologist.
You will read that medications, health issues, and previous anesthesia reactions are some of the important things to discuss with your anesthesiologist (or doctor who will relay include them in your pre surgery report.) Before my transplant surgery, the anesthesiologist visited me in the pre-op area to make a final check of my medical history, to explain his role, to answer my questions, and to calm my fears.

I think that a way to be a good advocate, is to feel confident to speak up and ask questions. Making a list has been very helpful to me.

Deep breaths are good!
I think that April 22 is an excellent date for surgery. That is the date that I had my liver and kidney transplant surgery, 12 years ago.
