Just got an old value of TSH from the UK. It was 2.87 mU/L on 9/10/14.
It’s probably always been on the high side, rather than rising rapidly in the last few months. So scratch my theory about a bad reaction to increased iodine intake.
@vincentv Are you sure your problems are hormonal? The numbers on your old thread didn’t look too bad, so it could be something else. Depression and low T have pretty similar symptoms.
