SO PLEASE HELP ME TO COME OUT OF THIS.I AM ALSO DOING WALKING AND YOGA REGULARLY. [/INST] Dear We understand our concernsYour problem was due to thyroid over secretion. Thyroxine clears the problem for the time being. Your thyroid gland is supposed to be producing thyroxine. It is not doing its duty, and therefore you had to take it as supplement. Stopping it will naturally bring back the symptoms. Because your thyroid is still in its old state. Listen to the advises of your physician and don't take decisions yourself. Wish you good recovery. </s>
