Heart surgery in February 2026. Prescription for 12.5 mg metoprolol twice a day. Tried and tried again but had to stop it. Dizziness. Anxiety. Panic attack requiring trip to the ER. I know it’s a small amount, but I’m gonna try to go without it for a month. BP during rehab is typically around 115/65 120/70 heart rate is in the 70s without the metoprolol.
