Holy crap, 7mg to 0 cold turkey? As said before, I'd consider that dangerous. Maybe the Klonopin helped you over the withdrawal hump.

Regarding your question of a replacement, I've had decent success with gabapentin helping to control my anxiety. I've been prescribed it to help with nerve pain, but it does have an overall calming effect associated. I know some psychiatrists use it for GAD symptoms, and I've also heard of it being prescribed as a mood stabilizer.
