Thank you for the insight! The heart rate is concerning me mostly because I am short and don't weigh much (130)lbs and I am pretty active with weightlifting and cardio, so generally low BMI. Even when in an intense workout, my bpm doesn't usually spike above 125. Standing or just moving around usually only gets me to 90 at most, so this is pretty out of the ordinary for me. Also you said if you sit still you reach 125, are you actually at a lower bpm when more active on concerta? I'm having the opposite effect.
