Thank you all! No, I'm not on any thyroid meds (never taken any).
Just some strange symptoms (mostly tiredness that we're all familiar with!). I'll be exploring other possible causes, so will hopefully get this thing nailed!
Btw, I had these done at Blue Horizon (the full thyroid profile).
Not sure! I know you cant overdose with B12 as any extra is flushed through but that's not the same as being high. Tiredness though can be because you are anaemic so the red cells aren't carrying enough oxygen round your body or you aren't storing any iron properly. Your GP should test that if you tell him you are tired.
