For the first year after being diagnosed with an under active thyroid I felt very unwell. My GP eventually referred me to a wonderful consultant who has allowed me to select my own dose of thyroxine judging by how I have felt instead of blood test results.
However, after two years I have now been passed onto another consultant who insists I must reduce my dose as all previous blood results are consistent with over-treatment. I have been told the aim is to normalize my free T4 & T3 and to avoid TSH suppression.
I have quite a stash of thyroxine and obviously want to stay on my present dose as long as possible.
My question is how long before my next blood test should I think about reducing my dose? Is this something that takes months or could I reduce literally the week before in order to get a lower result reading?
