I was pretty quick...went to see a doc, he told me about the need to see a counselor and get their approval. About 3 weeks later I had my first appt; it ultimately took 4 appts, one week apart to get the letter. (The fourth appt was just to hand me the letter).
Two weeks later I saw the doc again, that afternoon went to the pharmacy and got them. (I will note that my pharmacist did ask, "I know what spiro is for, but I don't know why you have an estrogen Rx...you do know there will be side effects, right?")
So all told, using the informed consent model, 8-9 weeks. In my case.
And smiling ever since.
