To me it seems like it helps with some of the physical symptoms of anxiety, but not so much the anxiety itself. So, it's efficacy depends a lot on the pathology of a specific individual's anxiety. For many people the physical symptoms of anxiety become self reinforcing, and short circuiting them can stop the anxiety. For folks whose anxiety takes a different path it may still be slightly effective but not quite as much.
