Propranolol has been great for me for the physical manifestations of anxiety (not as much for the feelings of anxiety, if that makes any sense). In fact, I hadn't been sure how well it had been working when one morning at work I noticed that a piece of paper I was holding was shaking and then later my legs were shaking, all from anxiety. I realized I had forgotten to take the propranolol that morning. So anyway, I think it's really really effective for shaking related to anxiety.
