Hi, I am a old bypass & stent heart patient & have been put on 2 new meds ( Norvasc & Lopressor). Since taking them i have been having lightheadedness. Thinking it could be from the Lopressor, I tried taking it at bedtime but had frequent bathroom trips, so I stopped it. The lightheadedness is still a problem, so I am wandering if it could be from the Norvasc. I am a snowbird & my doctors are in Pa.. I intend to see them when I get back home but til then, what do you think about the lightheadedness
