What other drugs are you prescribed? I am taking a small dose of Abilify, and in addition to my Klonopin I am prescribed Benztropine, which kills the restlessness and added anxiety that the Abilify causes. It is not a scheduled drug and has no abuse potential.
Another drug which I saw already mentioned, is Buspar, which works like an antidepressant as it builds up in your system. I've heard mixed things about this one though, I've heard complaints of it being too mild, especially when combined with a typical, nonnarcotic anti-anxiety medication.
