I went to the endocrinologist today and we talked thru all the options. She said she is OK with giving a low dose of the methimazole (which I may or may not be allergic to - or it may have been too high a dose). I will be taking 10mg a day, whereas before I was taking 40mg a day. She also wants me to take a zyrtec with it..
I cancelled my surgery for Tuesday, I will start taking the medicine today, and in two weeks I go back to the doc to see how my liver is doing. If it is bad or has gotten worse in anyway, then I go off the meds and schedule a surgery (she said I could wait until September as long as I stay on propanalol.
The next two weeks are full on health mode, hopefully some acupuncture (some say it works), and the new meds.
I feel really good about this decision. Keep your fingers crossed that all goes well in the next two weeks..
