Hi everyone, I am now one month post thyroidectomy. Blood work two weeks post op were incredibly normal. Endo started me on thyroid replacement hormone therapy of Synthroid .5 once a day. Taken on empty stomach each morning faithfully. I see the doctor 4/9 again but boy am I dragging. Tired from start to finish, very low energy, which is not loke me at all. Anyone have this problem? Do I need a higher dosage you think? Thanks.
