I take Metoprolol Tartrate 25 mg BID. When it nears time to take my second dose, maybe an hour before,I feel like what I can only describe as a pressure or ache in my heart as if it's telling me it's time for my next dose.I know that sounds kind of weird and was just wondering if anyone else has had that happen. The pressure feeling always goes away about a half hour after I take my night dose andrarely if ever happens with the morning dose. I know weird right?
