I was under the impression that Klonopin is not supposed to be used longterm. My doctor told me the drug can be addictive and wouldn't prescribe me more than 2 weeks worth for temporary anxiety that was supposed to be a side effect of Lexapro. I've also spoken to someone who started to experience several side effects after years of using Klonopin. I would talk to your doctor about this and see if there is another possible anti-anxiety drug you could try.
