Has anyone ever taken metoprolol tartrate for anxiety? I used to take it for my high blood pressure but I no longer needed it I haven't taken it for about 3 years and I noticed while I was taking it my anxiety went away and when I stopped it came back. My doctor prescribed it to me again but this time only to treat my anxiety. I don't have high blood pressure anymore so I'm kinda scared to take it. I will only be taking half of a 25mg in the morning and the other half before bed. I am worried if I haven't taken it for so long if I would have side effects because when I first took it, I didn't get any side effects?
