I&#x27;ve been using extended release propanelol daily for the past couple years as part of the treatment for chronic mixed tension migraines.  I&#x27;d been struggling with migraines leaving half of my body feeling extreme muscular tension 2-3 times a week.  I can&#x27;t comment on beta blockers effectiveness in treating anxiety, but it does seem to have a powerful effect on soothing the nervous system without the damaging side effects of addiction and impaired memory when I was taking Xanax or Valium.
