She increased me only 25mcgs (Cytomel) at first and similar to your experience, I was very warm within days of starting the additional T3... then the warmness leveled off (all but the night sweats). When she increased it again, the warmth came and stayed. My friends tell me you can hang meat in my house and the cat seeks all manner of covers to climb under. I, however, feel much better. For the first time in 8-10 years, my hair, nails and skin are back to normal...the energy is still somewhat diminished, but much improved. I also have Fibromyalgia, an energy zapper also, so I suspect the remainder of the fatigue is from that. One night of poor sleep sends me back into low energy oblivion. I also have had an interesting thing happen in the last week...I ran out of synthroid a week ago and have just been lazy about getting it refilled...(that and money has been really tight lately...). I have really bad headaches, 2-5 days/week, and have since my thyroid died. Well, this week while off synthroid, I have only had one headache that required Cafergot. That's a record for me...almost a week with no headache!! Does anyone else have any similar experience? Could I be allergic to the filler in the Synthroid? I refilled the synthroid last night and will begin taking again today...If the headaches return as before, I am planning to try Armour. If anyone on the board has had a similar experience, I would greatly appreciate your comments. Many thanks, Kathleen in Carolina
