Been on the above near on 3 yrs, anyone know why they are increasing it and what is causing me to crash through the floor again? I exercise daily , limited diet feel like I can't do much more....noticed that diabetes has a connection to thyroid so asked them to test for that too, result in tomorrow! (family history)....any advise would be good! Live in UK so they only test T4 and I have no idea why they don't test T3 as well, it seems absurd. Thinking of seeing a Specialist, should I ask to see one? Can't go on with symptoms and merry go round of feeling good one min and crappy the next, running out of idea's on what to do, just need help!
