I have been on toprol 100Mg for over 2 years. If you feel drugged and cannot function tell your doctor. And by the way have you read all the posts of the side effects of this drug? If not perhaps you should. I have been switched to a different blood pressure medication. This is day one of the new medication and I can finally breath better. You havent said how long you have been on Toprol. If you have just started taking it I would discuss it with your doctor and ask him why your on it. If it is just to lower your blood pressure....you better run like hell and find another doctor. This stuff is poisen. And I am sure at some point in time you will find class action lawsuits against the manufacturer. Please I beg you do what you can to take charge Doctors are not God...It is your body. If it doesnt't feel right to you it's not. Listen to your body and research every pill they try to give you. Good Luck
