before vertigo few weeks after taking toprol I felt dizziness and not steady on my feet and problem of memory could not remember things or forget names of people that I have known all my life. In other words do not feel good. This is ongoing, even after visits to ER, family doctor, and EENT specialist. All the doctors are saying its not side effect of the drug but I'm concern that it is. Any advice for me. Cannot go on with this vertigo for ever... help!
