Because I'm supposed to have it in November

They said I got alot of blood work to do, I can't take my medication for 3 weekscause of some radiation pill and scan so they're gonna inject thyroid hormone into me...Umm ok That sounds scary for some reason....

I have to be on a "low iodine" diet which means no meats.... So uh what the heck am I supposed to eat??? I rather eat nothing for 5 days then eat pasta... Seriously. lol.

Anyone have experience with this? I so don't know what to expect ..
