I had been experiencing what felt like hypo symptoms during the day - fatigue (sleeping much of the day), weakness, dizziness, hot flashes, feeling cold, weight gain, puffiness in my face - but then also experiencing hyper symptoms
especially at night - palpitations, anxiety, insomnia
, heat intolerance, etc. Is it possible that I cycled through both? My doc went by the numbers and finally decided I was hypo - my TSH was finally high after several normal TSH and T4 and T3 tests.
