Jared I have been taking about 1/4 off it it, it's hard as they are not scored to be exact. You got me thinking, I lost 20lbs recently, maybe that is why my low BP has been worse? I'm not big either only 4"10, so maybe blood pressure avg. is for bigger people? I don't want it too high like my pulse due to bad hearts in my family and I know lower is better, but it's been WAY too low. My PVC's have been more often, those scare me :-(
