I've been taking propranolol for my heart palpitations, aching and generally making me feel ill. I tried cutting down/out and supplementing with magnesium, (worked during the day), however whenever my heart rate drops low during sleep my heart wakes me every time, thrashing inside my chest as if my body is telling me something. Nb normal blood pressure. Is this another gift linked to PSA or am I just unlucky? I'm waiting for further tests but been prescribed 120mg Diltiazem which I'm worried about taking!
