Yes, Knotty's response was very amusing... I laughed myself. Wasn't ever suggesting I was going to ask a trainer to diagnose me, I was going to ask if he'd ever heard of anyone else having the issue.... the goal being to try to figure out which direction to seek help, if needed, because starting at a GP is just ridiculous and a complete waste of time and money.

The question was more a curiosity thing - it's been happening for years, happens when my heart rate gets up above 180, which is rare. As for Darwin Awards...thanks sunshine, but no worries, I'm not passing these genes on, I didn't breed.
