Im super tired too. I know part of mine is from getting my thyroid removed but some is from not smoking. I have to see my dr for blood tests all the time to monitor different levels of stuff. Also my calcium went super low because apparently they startled my parathyroid and its not producing calcium like it should. Everyone is different even with some of the same diagnosis. Our bodies react differently. Im trying to be gentle to myself early in my quit but also dont want to get used to it. Its a delicate balance
