Hello Vanessa, I think you are wise to hold off on RAI for a while until you try something else.My doctor insisted that I had RAI but I have resisted so far. I have been hyper for 4 years and only started meds 2 weeks ago. I dont know if they are working yet since I did not get any blood test as yet. I found the website ithyroid helpful. I have started taking copper supplement along with calcium,magnesium and others..Good luck
