Hello @italianwitch48

I had a lot of side effects with Metoprolol as well, especially the insomnia, nausea, dizziness, etc. I called my doctor and asked if there could be a substitute med and he prescribed Atenolol. It is the same type of drug, beta blocker, but did not cause the side effects like the Metoprolol did.

How close to your bedtime do you take the second Metoprolol?

Many of us on Connect have posted about Metoprolol and it's side effects. I hope you find some relief soon.
