I was taking 500 mg of magnesium, 500 mg calcium, 100 mg potassium for about a five days, as well as my medication Meditoprol. On the 5th day my blood pressure went to 117/76. Which is what I was trying to achieve, lower blood pressure. Well, the next day my pressure spiked to 195/110 and for the past 3 days has not come down. I have since stopped the magnesium cocktail but my pressure is still high. Any clues as to why? Thanks, Nik
