6.5 weeks post TT due to papillary cancer, been on175mcg levo since, suddenly turned into a jittery, weepy, wobbly boiling hot insomniac. Resting heartrate 93bpm. Palpitations. Oncologist says I need to stay on dose for 9 months to discourage thyroid cell growth. I can't stand 9 months of this. No results to show you yet I'm afaid. Please help!
