Doctors blamed my first afib episode on dehydration. I had been very sick, could not eat or drink for days, and just experienced the highest fever of my adult life, nearly 105F. A few hours after the fever finally broke, I went into afib.

At that time, I was on an opioid pain killer for an abscess. The next time I was on an opioid pain killer, years later, I also had an afib episode. So I wonder if maybe I have some sensitivity to opioids.
