Propranolol long term side effects?

[Slick]

I have been on propranolol 80 mg ER for years as a blood pressure med prescribed by my primary doc.  No other doctors have ever questioned this, even my surgeon.  I know when I have missed a dose due to the palpitations I get.  I assume it must work differently for people with high blood pressure because I have certainly seen my fair share of doctors over the years and none have ever expressed concern about taking it.   Just my experience.
