yeah I really think they will suggest trying to control it with meds first. Because sometimes it can go into remission and no further treatment is needed. I think they would really only start talking thyroidectomy or RAI treatment early on if the graves was extremely severe and non responsive to medication.
Best of luck for you appointment. it's a pity you can't get in til May, but hopefully it comes around quickly.
Hope you're feeling okay in the meantime.
