i take BC powders several times a day to help ease my fibromyalgia but sometimes I go overboard. I had a heart attack 9 mo. ago and aspirin is a part of my daily meds, but I take way more than recommended. Can this cause another heart attack? I take about 6 or 7 powders a cay and each contain 650mg of aspirin and 33mgs of caffeine. I know its not good but how bad is it actually?
