I was diagnosed with under-active thyroid nearly 3 months ago. I started on 50mg Levothyroxine and after a month I felt miles better. Had lots more energy and felt really positive. In the last two weeks though, I've gone back to how I felt before.
Had blood test yesterday and seeing the doctor next week. Nurse said my body could be getting used to the thyroxine and I may need to increase the dose. What concerns me is my levels were "borderline" to start with and if they are now fine, it may be something else.
Anyone had experience of this? I start a new job next week and I wanted to feel in tip-top condition.
