My test results have come back since starting Thiroyd 8 weeks ago. I take half first thing in morning and now recognise when I need the other half early afternoon. I sometimes feel low at teatime. My results are free T4 11.2 (12-22), TSH 0.04 (0.3-4.2), free T3 5.4 (3.1-6.8) and ferritin 63 (12-230). I was on 50mcg levothyroxine. Are these where they should be for optimal, I am not sleeping well and sometimes get stiff and painful joints although I went to a party on Saturday and danced all evening, it seems to vary from day to day. Sometimes I get muscle pains at night which keep me awake. I also need to eat bananas, I find three a day make me feel better.
