Anyone taking Cytomel & Synthroid for Hypothyroid? Taking Cytomel for about 4 months. When doctor checked thyroid recently, T-3 was in range, but T-4's and TSH were extremely low!! Doc has me adding Synthroid to the Cytomel, starting at 50 mcg for a week and going up to 100 mcg. If still no improvement in symptoms, stopping Cytomel. I'm at 100 mcg this week and very little improvement. Will drop Cytomel end of the week and stay at 100 mcg. Then he will retest. Does any of this make any sense to anyone? My worst symptoms are being extremely tired and feeling that my brain isn't working along with being so down!
