"Worst drug I've ever tried and the reason I'm scared of new drugs.
It made me have tachycardia. My heart was speeding at over 200 bpm sitting still. Worse if I got up to walk around or anything like that. I couldn't sleep because it felt like I was running. I would stay in bed propped up (because laying down made it worse) and occasionally drift off when I got so exhausted I couldn't stay awake anymore. This sleep only lasted about an hour at a time before I woke up again. Docs increased the dose saying I just needed to get used to it. It made it worse. I made them take me off of it after "giving it a try" for three hellish weeks."
