Hello @kancha
I'm under the impression that your doctor suggested the elimination of this med, is that correct? When I took metoprolol I had a lot of side effects as well. I was only taking 25 mg, though. My cardiologist substituted Atenolol and I felt much better. I do not take it at bedtime, but at noon which works much better for me.

As I have heart valve problems I take two different BP meds. One is an ACE inhibitor which is a marvelous drug to strengthen the heart's functioning and then the Atenolol, a beta blocker which keeps the heart rate from racing.

Have you reported the light dizziness to your doctor? Do you monitor your BP at home?
