I am taking many heart medications... Lisonopril, Metoprolol, Diltiazem, Simvistatin, Plavix, and Aspirin. What would happen if I suddenly stopped taking them? I am going to be without insurance soon, and need to know how to slowly stop taking them... really no other choice here. My last angiogram was fine, I do experience rapid heart beat, whenever I try to increase my physical activity. Are there any 'natural' ways to help me?
