I've been on both Ativan and Klonopin (Clonazapam). Ativan is really fast acting, so it's good for panic attacks, but it can negatively affect memory and cognition. It also doesn't stay in your system very long. Clonazapam is slower acting, and stays in your system longer, so it's better for managing ongoing anxiety. I take it, in addition to my other meds. I take 1 mg 3X daily and 2 mg at night.
