@windyshores thank you for your response. I haven't heard about the "pill in the pocket" Eliquis. That is a great suggestion for him to get. He also has a smartwatch and we are going to add the Atrial Fibrillation monitoring ability.
I also will get "The Afib Cure" by Cardiologists Day and Bunch. We have him on magnesium for sleep. Will look into your other suggestions too!
I so appreciate this mayo clinic discussion group and everyone's help.
