I wrote in the past regarding my falling asleep with extreme ease (sitting up watching TV with a glass in my hand). Apparently, not many of you have a similar symptom post total thyroidectomy. All my blood levels are normal (synthroid 175 mcg). I recently went on a low dose antidepressant and this has made a huge impact. I have never been clinically depressed nor very low energy. This antidepressant took away the problem of falling asleep at the drop of a hat. My overall energy level and mood seem relatively unchanged. Have any of you found that an antidepressant makes a big difference post tt?
