Risperdal can be used as a prn (as needed) med. Maybe your pdoc will be more comfortable with you using it that way if you let him know you tried it and it worked for you. Maybe some of the anxiety you have been experiencing is more of the "manic" or "rapid" feelings and that's why it hasn't been responding well to the Klonopin. The more you tell him about what's been going on, the better. You may want to write everything down before your visit so you can make your case.

If he is really against raising the Risperdal, even as a prn, you could try a mood stabilizer. That would be a good option, too.
