After two weeks of taking the pills, I unfortunately experienced mild attacks of tight chest pains, tremors, tingling arms, shortness of breath, anxiety and
heart palpitations. I later found out from my endo that these were symptoms of an overdose (i.e. the same symptoms you can get from hyperthyroidism, overactive thyroid). A possibility of this may have been that I'm only tiny (4"11 and just under 8 stone).
