Recently I have seen great results while taking 25mg of METOPROLOL (Beta Blocker). I wonder if I can and have to take it forever. Of course, I'm ready to take it forever, but at the same time it's a bit scary. "Forever" means literally until the last day of my life. Can I arbitrarily reduce the dose while watching my condition? The doctor said it was dangerous to increase the dose and dangerous to stop taking the drug. He wasn't too concerned about reducing the dose.
