For about 2 weeks I have been getting palpitations. At first it was in the afternoon and evening but now I can detect them any time I'm quiet. I take 75mcg T4 and 17.5mcg T3. I was taking 20 mcg T3 but reduced it to see if any difference. I take all my meds at 7a.m. I remember the "TiredThyroid" graph where 1 dose took you way over range. Should I see my doctor, take my meds more than once a day or not worry. My last test was T3 5.87pmol/L (3.1-6.8) on 20mcg T3.
