high blood pressure
"Elevated blood pressure and increased heart rate due to long term undertreated high blood pressure. Metoprolol worked wonders. Been on it for a year - the side effects are strange dreams (not scary...just strange) and exercise difficulties. My doctor recommended sticking with 80% of exercise target heart rate. If you're having side effects, give this medication a couple months to work. It will get better. Make sure your doctor monitors your triglycerides and blood sugar while on any beta blocker. My triglycerides shot through the roof, but now under control with fish oil. "
