YOUR SYMPTOMS SOUND LIKE LOW pH OR LOW OXYGEN AND A HUGE KILL OFF COULD CAUSE THAT, BUT I WOULDN'T THINK IT WOULD EFFECT YOUR HEART THIS WAY, UNLESS THE VALVES HAD WORMS, ETC.....SO SINCE WE CAN ONLY GUESS AND YOU STILL WANT THE PRODUCT, THE STANDARD IS TO CUT YOUR DOSE IN 1/2 AND SEE WHAT HAPPENS NEXT AND KEEP REDUCING UNTIL YOUR "OK" WITH WHAT IS HAPPENING AND NEVER GET IN A HURRY OR FEARFUL, BECAUSE THE ER FOLKS THRIVE ON THAT.
