I am new here. I was diagnosed with underactive thyroid when i was 9. I am 38 now. I have never really felt that the thyroxine was helping me and i currently take 400mg daily. The doctor always says my blood tests are fine and continue with the thyroxine. In the last year i have been more tired than usual and can fall asleep anytime for hours at a time. My toungue is swollen and my hair is falling out more than normal. I am also on 100mg of sertraline (anti depressant). I have been reading about Dr Skinner and wondered if anyone had any experience with him?
