Hi there. I am (not practicing anymore) an RN and if these people gave you a prescription for Klonopin to start and knew you used to take Xanax, I would just start the Klonopin.
I was myself just switched to Klonopin from Ativan. The good thing about Klonopin versus the short acting benzos like Xanax/Ativan is that they are more level. You will not have withdrawal if you can go 3 days without Xanax. Even though you have been on it for a year or so, the last dose you took is already out of your system and you can take the Klonopin without worry.
When you take Xanax, it works quickly, but also quickly wears off. Think of Klonopin as a smooth, stable agent that doesn't peak/fall and controls your anxiety better. It has worked much better for me so far, even though I didn't think it would.
I hope this helps. Good luck in feeling better. Long time stress and anxiety usually does horrible things to your body, I am proof of that.
