I am going through withdrawal as I taper off of Klonopin. Internal vibrations were the first thing I noticed when I started tapering, and even when I was in tolerance to the dose I was on for many years. I belong to a benzodiazepine support group and many of the members, there are 3500 of us report these internal vibrations. It’s the strangest feeling. Be careful how long you are on Klonopin because you can become dependent on it. I just watched this great documentary with Lisa Ling on the discovery channel, called “the benzo crisis”, and one of the women interviewed reported these vibrations. I wonder how many medication’s can be linked to this kind of symptom? I know antipsychotics for sure. And I know it’s miserable.
