Hello, I am taking beta blockers. I have had a heart attack couple of days ago and I guess beta blockers I have to take as prevention. No one needs a heart attack, right? But, even in that short period of time, some side effects occurred, I had trouble sleeping. Although, I have to admit that I am not sure if this was because of the stress or because of the beta blocker.
One of the side effects is sleeping problems, but you are right, it might also be a result of your stress related to previous heart attack experience. I guess you should wait and see what the real cause of your problems is. If it is because of the medication, then you should perhaps inform your doctor about it and see what to do next.
