underactive thyroid
"Took levothyroxine for 32 years.  In last 3 years, the weight gain, bloat, insomnia and overall funk became unbearable.  Saw everyone is having similar trouble.  Quit, cold turkey, 2.5 months ago.  Feeling much better, immediately began losing weight.  They say stopping was supposed to be dangerous, but I had no issues.  Am not taking any other supplements."
