I've been taking Metoprolol for moderate high blood pressure since July2007. I've been dealing with weight gain....nightmares....sleep disturbances and more within weeks since I began. I wasn't sure what was going on with me. I'm 55 and attributed all this to some sort of midlife crisis or something psychological. I've contacted my primary care physician and will hopefully have an appointment within the next several days. In the mean time I was told to STOP taking the medication and that he will assess my BP and alternative meds when we meet for my appointment.
