I was put on propranolol for rapid heart beat caused by stress and anxiety. Doctors gave me 40mg in the morning at 20mg at night however I was only taking 10mg (naughty I know) lately I’ve felt I’ve not needed them so the last two days I haven’t taken any. I’ve just read up online that you shouldn’t just stop taking them that there can be bad side affects and even death! I’m now freaking out! What do I do?!!!!!
