I have been taking Lopressor 25 mg. twice a day. My cardiologist is weaning me off in the next two weeks and has cut it down to half of the 25 mg. pill twice a day. I'm feeling anxiety and having severe insomnia. If this is caused by cutting back on the Lopressor, will this go away soon? Will it get worse when I'm completely off the medication? I don't normally have high blood pressure. I was put on Lopressor because I had a stress heart attack. My heart is now back to normal on an echocardiogram, so my doctor is taking me off the medication. Thank you very much for any advice you may have.
