Hi there, thanks for asking. Your doctor is right. You can discontinue the medication if you do not have any stressful situation in the family now. Metoprolol
is a medication which does not enter into the brain so much and the most part of its effect is on the peripheral system, like heart and vessels. It means that it controls the manifestations of the anxiety
over the body and so it brings a peaceful situation for your brain since it does not feel any alarm from the body. When somebody is under stress, any change in this medication could lead to the anxiety rebound, otherwise he/she can not to take it. I am glad that you have passed the stressful situation and wish you a good health.
