panic disorde
"I have been on Klonopin for about 6 years now, started on 2 mg a day and have been on 4 mg a day for around 2 years now. It works great.  I started suffering from panic attacks around the age of 15 or so and it lasted until I went on Klonopin in my mid 20's.  I tried many anti-depressants (Paxil, Zoloft, Buspar, etc) and even Stattera.  None seemed to help.  I can tell you that I will be on this for the rest of my life, it has allowed me to be the person I should be."
