Began feeling GREAT when I added in t3 (150 t4 plus 25 t3, added in gradually over a couple of months). Even started running again, every day. Eventually felt a tiny bit hyper (diarrhoea, trouble shutting off my brain at night), confirmed about a month ago by blood tests. Sorry, I don't have the results to hand, but I was told I was just a little outside the range (I remember I had a v low tsh, .01 or similar).
Doctor was happy for me to stay a little hyper as long as I was feeling so well, but advised that I would eventually want to get back in range due to risks associated with being hyper (bone density, heart, etc). Advised me to very gradually reduce the t4, like reducing it a tiny amount every four days, then every three days, etc. The goal was to be taking 100mcg t4 in January.
Now, only a month later, I barely had the chance to reduce the t4 at all but I feel hypo. I'm no longer running - tired, feeling a little blue - and I'm constipated. I suspect constipation more than anything will be my 'tell' for being hypo, as diarrhoea was the 'tell' for being hyper.
The only thing that has changed is that I'm back in the UK after six weeks of being abroad in a warm, sunny climate. In the threeish weeks I've been home, I barely had the chance to reduce my meds at all (I took a slightly reduced dose only twice, every five days), so I don't think it's down to reducing. My pulse and temp have been normal throughout, even when I was hyper.
I'm back on 150 t4 to avoid feeling any worse. Still constipated, even on my usual dose.
I guess my question is, can my needs have changed in the last month? Is it possible that I now need the dose which was a little too high only a month ago? Is it time for another blood test already?
Thanks in advance for your help and support. I feel so sad after feeling so well. It's somehow worse to feel I'm going backward than it was just to always feel a bit rubbish.
