Ok...yes when i woke up the other morning my HR was 137 bpm; sometimes when i'm sitting, and i think i'm pretty relaxed, it'll go to 97-113 bpm. And lately, i've been feeling this one hard pound in my chest then it just palpitates. I don't get it. I've been trying to lay off the caffeine lately, and i have been on my same meds (Concerta 72 mg) for a year now, but i've never really noticed my HR as much as lately. I've been laying off exercise a bit so to avoid overtraining, but my heart rate is still a bit higher than normal sometimes
