Merry Christmas everyone! Can anyone help out, I have Graves' disease take 125mg levo, 2 yrs ago an endo prescribed T3 20mg to be taken in half dose each day, over the months I've tried T3 and I feel worse than Levo only, why? I am moodier, aching joints etc. I have stopped taking T3 again and feel a bit better in general, all opinions welcome. I will go back to NDT on the new year felt good on armour.
