"been on and off this medication since november 2014 after a stint of three days with no sleeping thanks to my chronic anxiety/panic disorder.  started out on 50 mg but i couldn&#039;t tolerate it, so i tapered it down to 25 mg and it worked like a charm. the first few days are awful with the dizziness, foggy head, just getting the day started can be a royal pain. however, i had some amazing sleep taking this, just hated the feeling of being drugged. i tried going cold turkey off this medication and let me be the first to say do not go cold turkey!  i was so sick and shakey, muscle cramps/spasms, severe vomiting, worst flu like feeling you&#039;ll ever have. i broke down and cut a 25mg into 12.5 mg.  muscle pain lingers but everything else is better."
