It's a hard place to be for sure. I'm pretty much in the same boat. My pdoc and T basically say that there's no reason I can't use my Klonopin more if I need to. But, honestly I'm most worried about being addicted to it even though there's not really been any reason for me to be worried about.

Just, not feeling anxious is amazing!

I end up taking one if I know I'm going into a situation that's going to trigger my anxiety. (Plane rides as an example). Then I kind of play it by ear for other situations.
Do I need to be able to act like an adult and not shut down?
Am I having physical symptoms (chest pain is my big one)?
Have I used non-medicinal coping strategies?
What is causing the anxiety and will it end soon?

I've taken to being more liberal with my Klonopin, but I think part of that is realizing that I am an anxious person and life is better when I'm not wound up constantly.
