I had akathisia and my pdoc put me on propranolol, a beta blocker. It's main function is to reduce blood pressure but it is also used for movement disorders (akathisia) and, surprise, anxiety. I had been anxious prior to starting it and it stopped soon after starting propranolol. I looked it up in an online PDR and found out it is good for anxiety. It is not a benzo and addiction is not a problem. The only problem I have had with it is orthostatic hypotension... which means you get dizzy if you get up too fast. When it happens I just bend over to lower my head for a minute and it goes away.
