I take Magnesium and Coumadin for my heart as well as Beta-Blocker for AF.
But if I take even a bit of Codein or coffein - my heart would prevent me from sleeping or leave even that is how sensetive I am to any stimulants. I honestly don't have any relieve from all I take. Hopefuly they will find something else for me.
Even my PK (I had spinal fusion) have to be any stimulants free.
I am glad you are doing better!
