I've been using ECA for a couple of weeks now, and I wanted to know what kind of side effects I should be concered about. Also, what would a dangerous pluse rate and blood pressure be? I've been consistantly between 100 and 124 beats per minute today, and I was a little worried about that. I checked my blood pressure and it's been around 160/80 this evening. Should any of this worry me?? Thanks for the help!
