I thought it was pretty much a fixed medical aspect of quitting smoking that it would take your body years/decades to regain the ability to regulate adrenaline production properly. That you would suffer occasional adrenaline surges during that period. I was beginning to wonder if they'd ever subside. So it's good to know someone doesn't experience it. Though I have become used to them over the years and, in some situations, are not all bad.
