high blood pressure
"I began taking metoprolol about 2 months ago, 25 mg daily.  I had a hard time getting used to it. Stupidly, I stopped taking it after the first week, I ended up feeling so bad I had to go to the ER.  Since then all my problems have been side-effects.  A few hours before I am to take my next dose I begin to feel depressed, very cranky and angry and generally just awful.  Once I take the medicine though those feelings tend to go away.  It also upsets my stomach and I have had a mild loss of appetite.  I have also noticed that some foods taste different.  I am also having a problem staying asleep, but I seem to fall asleep easily.  So I am up and down all night.  I am not happy on it so I will be asking my doctor for something else."
