Been taking Levothyroxine now for 18 weeks, started off on 25mcg and been upped by 25 every six weeks. My TSH level has come down from 7 to about 3.5 but since taking 75mcg I have felt much worse. I am really anxious, sickly and just feel completely exhausted and washed out.
I have my next blood test next week and a GP appointment a few days after, not sure where to go next, concerned upping dosage may make things worse again or is this normal?
Need some advice as I'm really confused what to do next.
