I had atrial fib. after a 4 way bypass. They administer rat poison for
a few days to make sure you don't form a clot. After the electrical
signals settle down the AF goes away and so does the need for an anti-
clotting agent.

I smoked for years, just got lucky and haven't had one since St. Valentine's Day 1996.

If you smoke, QUIT! Stick around and toss insults like the majority here.
