i went gluten free last nov, started having headaches in April, tsh was nearly suppressed and t4 was 21. Discussed with my dr and reduced from 150 to 125 Levo. Headaches have stopped but have tinnitus in ears, rushing pounding sound, my normal pulse is 50 bpm now over 60 , heart feels like it is racing, very tearful for no reason and trouble sleeping, but not tired. Do others think these are signs that I am still over medicated.I am scared to reduce again in case I go hypo. Was thinking of reducing to 125 and 100 on alternate days.
