Been off this medication now for 4 months and have realized I don...

hi! i have been on this med for about 4 months now, started taking with coreg due to congestive heart failure after having a baby. i am 20. i now am having TERRIBLE headaches and neck pain, sometimes feels like a pinched nerve. the headaches are almost always constant, and are definately affected by movement, i.e. sitting or standing, and my vision gets sometimes blurrry... but my bp is doing fine. are these the headaches you refer to? around the back of head, near neck, and sometimes in temples? talked to nurse today at cardiologists office, and she said doc said to stop it for 6 days and call back.... just wondered if this was a similar situation. also, have a dry cough that comes and goes, sometimes for about a week, then gone. i also have insane anxiety, i can't make simple little decisions, and freak out about everything! just sounds like we are having similar side affects... .just trying to figure out, out of my 8+ daily meds, what each side effect may be from. thanks so much for your time!
