"Propranolol only takes a matter of minutes until you feel it &quot;kick in&quot; and slow you down.  Watch out for the first time, it&#039;s like somebody hits your brakes!  I&#039;ve been on it for 5 years now and the extended release capsule (160 mg) lasts right at 24 hours on me.  Only big side effect I have is short breath sometimes and impotency at first.  After a few months my body adjusted, I feel normal.  Don&#039;t miss a pill though, or you&#039;ll feel your heart race and a little anxious.  Benefits outweigh risks."
