Cytomel and shortness of breath

I am taking Cytomel and really don't like it. Shortness of breath, itchy skin, cramping in my legs, heart palpitations, headaches, nausea and insomnia.

i was prescribed cytomel as an adjunct to noretriptlin 25mcg twice daily/ I do not have any thyroid problems. Both above drugs were prescribed by a psychiatrist. I began to have brief loss of vision followed by extreme weakness and sweating. these symptoms occur I am currently undergoing a series of cardiological tests because my primary physician found an irregular heart beat via ekg. I have always had an irregular heart beat. All my physicians are aware of all the medications I take which includes a blood thinner. Most unfortunately, am having difficulty connecting the time frame to the "side effect" and datae of beginning the cytomel. I realize I can make the connection by calling the pharmacy tomorrow. I also have an eye disorder with no cure and have lost much of my peripheral vision so at first I thought there may that relationship. But I went to the doctor when I realized I was also experiencing the fatigue, shortness of breath and something quite akin to hyperventilation. I will have my 69th birthday this month and thought my body and mind had a close relationship, but I am beginning to think they have become arch enemies,bent on just confusing the hell out of me.The tests with the cardiologists have been on going for almost two months with no results or diagnosis given.that important phase is due August 27. It is a good thing that patience is one of my virtues although brevity is not. Any comments please and thank you

chest pain, shortness of breath from very little exertion, feels like increased heart rate, diarrhea,all over itching. Given as a supplement to a lowered dose of Synthroid which is causing me to be Hypo-symtomatic again. Notified my doctor and discontinued the Cytomel. Dosage=5mcg twice daily. Tried it for 2.5 weeks.
