I was wondering if anyone has experienced this. I have been dx for four years and about the same time I started on thyroid med. At my last Dr. appt my Dr. mentioned my thyroid test was just at the low side of normal. He asked some questions about enegy levels and doubled my dose for a six week trial. Within one day of the new dose I feel so much better. I still have times when my dx overcomes me but I just feel over all more alive than i have in a long time.
