Clonazepam
anxiety
"Clonazepam probably saved my life.  I've been on it for twelve years.  It was originally prescribed to me because my antidepressant was not doing the job of suppressing panic attacks.  Clonazepam worked incredibly well for me - for 12 years, .5 milligrams is all I need to stop the worst of panic attacks.  I've never noticed any side effects, save for some drowsiness at times.  The only downside that I've experienced is a mild physical dependence.  If I go more than two days without a clonazepam, I start to feel kind of jittery, restless, and tense.  These periods of physical dependence have been easily remedied though, by simply easing up on the dose over the course of a couple of weeks."
