hi doc, I have been taking thyronorm 25mcg. for almost 6 months now, i have had hysterectomy done. After taking this medicine i feel i have become more forgetful, have gained weight, & my focus when listening to some important talk is just not there. i have been a very alert person, full of life , energetic, happy , now all of this is so far fetched. i feel tired easily, feel low & depressed, worry too much, and feel terrible. Is all of this because of taking thyronorm 25mcg. i tablet daily. If my thyroid tests are normal, can i give it up. Will i be my old self again.
