On my own, I started 600 mg daily of magnesium oxide since I had heard it might help with muscle weakness. While I was taking that, I ran out of beta blockers and tremor did not return. I figured it must be the magnesium that had been keeping my tremor under control all along. Since then I have been off of the beta blockers completely. My tremor is better as long as I keep taking the magnesium. And my strength is also improving.
