So I’ve been drinking coffee for past few years which included expresso shots totaling ab 400-500mg a day. Now I have cut back since I have been battling high blood pressure. However, I still have high blood pressure on 200mg of caffeine. Could this be the cause of blood pressure issues? Did I do permanent damage ? I’ve tried to stop 3-4 days and actually not much improvement. Would it take longer to clear it out of my system ?
