Hi, @singitsoft, I have to agree with @afrobin @soliloquized and @heathytoday. Along with supplements make sure you maintain a healthy diet. For me the Metoprolol was causing additional symptoms besides the tachycardia. I started with dizziness, nausea, extreme weakness, I attributed it to another condition but since I started the tapering and a heathy diet and exercise as much as I can for now I feel better. I would definitely consult my doctor before quitting the metoprolol and NOT quit cold turkey depending on how long you were taking the Metoprolol it can cause additional heath problems......
