I've been having crippling anxiety to the point I can't even catch my breath. It's like a bad asthma attack. I take 150mg twice a day and I'm staring to wonder if it's the culprit. I'd like to stop taking it like tomorrow but pdoc gets pissed when I play around with meds without talking to her. I might do it anyway though. This anxiety is too much. Good luck pirilin, I'm sure you'll be fine. In my experience it's never caused withdraw or anything.
