I am 53 years old and have been on thyroid med since late 30s and am going through perimenopause and I have taken at least 2 blood tests since August 2017. I feel energetic, fit, very little anxiety. My doctor(s) has changed my dosage from 120mcg to 88mcg to 75mcg. My TSH is now .07 but it was 12 on 10/30/2017. I am tempting to see a naturopath doctor because these doctors don't know anything. I don't know why I am feeling great but my test result swing from the extreme left to the extreme right of the spectrum.
