Possible: Hi. There's huge individual variation in response to any level of thyroid hormone replacement. Some of those symptoms COULD be your body's response to having a TSH of 0.53. I would try lowering your l-thyroxine dose to 50 mcg or 25 mcg and see if your symptoms improve with your TSH coming up a bit. However, many people feel fine with a TSH of 0.53, and it's possible your symptoms are not thyroid
