Let me jump into this conversation, John. I fully understand how you feel about always being involved in hospital and medical stuff in general, so sorry for that. Just wanted to tell you that my husband has had atrial fibrillation for quite a few years. He's now on HT and RT due to PC relapse, as well as on medication for his atrial fibrillation. So far so good. I mean, as long as you follow your doctor's rules it's ok, do not panic. Just have it controlled.
As for statines I guess they are related to high cholesterol, I also take them myself. And then folic acid... We're not pregnant but we go old, John. Lack of biochemical resources often come, I'm afraid this is a tribute we must pay for having arrived at this old age.
My intention in to encourage you. Coping with desease is not fun of course, but don't feel so scared about your atrial fibrillation. My OH is 73. Right now he's working really hard in the garden. Cheer up!
Best to all of you,
Lola
