Metoprolol
"I was prescribed hydrochlorothyazide to lower BP. Within 2 weeks I had tachycardia and went to the ER at the VA. After about 8 hours the tachycardia went away but the idiots at the ER didn't see fit to take me off hydrochlorothyazide. So, within 2 weeks I had another bout of tachycardia and went to the ER again. This time I was put on metropolol and still not taken off of hydrochlorothyazide. Instead of tachycardia I ended up within 2 weeks with arrhythmia that was so bad it felt as if my heart was going to explode through my chest. I kept having bouts of arrhythmia every 2 weeks with my heart exploding with every heartbeat. I used a food protocol changed everything. D-ribose does the same as metropolol with no side effects."
