How to Respond to Dr's Possible BS?

I've been doing the Iodoral for over a month now. I'm HYPO and had blood drawn on Friday for next week's appointment. What if my thyroid levels are crazy from starting Iodoral and she suggests more meds? What is the appropriate response if I'm not interested in that route? I know it's my body, but I also don't want her thinking I'm cuckoo. I have to see her for my type 1 diabetes as well. She's aware of me taking "iodine", but doesn't know my goal is to eliminate synthroid. Tweet
