Hi, I have been taking 100 mcg thyroxine for 6 days & 200 mcg for the 7th day of the week. The additional 100mcg on the 7th day was only for a month. After a month the endo ordered to see only TSH and the result showed TSH of 0.3. So she decreased he dose to 100mcg per week. But I have night sweat, palpitation, hot flush sometimes feeling cold and disturbed sleep. Is the perimenopause to blame? If so is there any remedy to reduce the symptoms? What about taking thyroxine at night? Does that help?
