I also take Thyroxine. Have taken it for about 12 years. Dose varies alot, used to take 200mg now down to 100mg. I too dont believe the blood test results and did quite a lo of research on this, just because we fall in between 2 numbers on a scale does not necessarily mean we feel OK in ourselves! I get quite tired, dont sleep very much at all, and well the mood swings. Yes, Jane 2008 the symptons of thyroid probs and menopause are roughly the same - very confusing!!! Will be interested to hear what your specialist says Denzy, I too have a mirena coil - we must chat more!!!!
