Soz to hear you've had u/ active thyroid so long..
My family history is of overactive thyroid tho i am under..
My mum had massive op when i was four to remove some of her thyroid...it was a tricky dangerous op back then
My Nan died aged 52 of untreated overactive thyroid.x
ADF has worked so well for you in the past Bean,it wd be good for you to be back on it,as long as you don't find it too stressful x
