The pounding and extremely fast heartbeat are no better and after 2 weeks my Dr had me increase the dosage to 2/day (one in the am and one in the pm). Now I can't sleep and I am exhausted! I cannot find any mention of insomnia in the side effects and I even checked for drug interactions. Nothing. My Fitbit Charge HR shows my heart rate still goes up as high as 130 BPM even when I am trying to sleep. Help!
