Hello, this is my first post so be gentle with me! I have a couple of questions. I was diagnosed with graves approx 2.5 yrs ago provided the meds to try and stabilise (carb and prop) however last consultant visit advised rai would be the next option as readings were tsh0.01 t4 51 and t3 18' basically i have another appointment on 12 June and i think the rai would be agreed. Ive been taking 50mg carb for the last 3 weeks to reduce, I know bodies are very individual but do any of you have an idea how long it will take to go hypo, also if i ask is the consultant likely to give me a combination t4 t3 instead of t4 alone. Or do i wait to see if the t4 works!!! I,m a little apprehensive so say the least because I'm expecting to be much worse than i already am!
