I am not a doc. But I have tapered off two meds in the past that I was told I needed to take til doomsday. One comment said to taper from 100 to 75 mg. I don't know if they are pills or capsules, and I AM NOT TELLING YOU WHAT TO DO, only what I would do. I would decrease the quantity, by taking a small sliver off, or a bit less in the capsule for a couple of days. And keep doing until not taking. No cold turkey, slowly. And I PERSONALLY would not be consulting the doc that gave them to me. I would just do it. BUT THE DECISION IS YOURS.
You live in your body, and no one know better than you to speed to do it. Vegetarians who do not eat meat and animal products, do not have HBP. I eat a little chicken and some dairy, but not much and my blood pressure is if anything, too low.
Regarding your AFIB, are you drinking or drinking ANYTHING with caffeine? Coffee, tea, cola, Mountain Dew which has more caffeine than colas, chocolate? If so, quit them, and you may find that your AFIB is gone. That is the case with me.
Let us know what you do and hopefully good results.
Regarding your other meds for HBP,
Thank you!
