I was on Metoprolol for
about 2 years and had some weird experiences with
it. For several months, I was taking
50mg once daily. I could not take more than that. It seemed like every day, about 20 hrs after taking
the dose, I would start getting a pattern of 3 normal beats, three hard beats, three normal beats, etc. for several hours until I took the next dose. It meant taking
a dose every 20 hours and that got really difficult.
