I decided to stop my thyroxine over 10 weeks ago now as my last Dr increased it too 150 mg. I was on 125 for 26 years and it worked for me . So recently i had another blood test and it showed over active so my new Dr decreased it to 75mg . I got so fed up being dominated by tablets and Dr interfering with my dosage i took matters in to my own hands and stopped them full stop. So what i want to know as anyone had side effects from stopping there Thyroxine??
