Thanks for saying that, I had no idea CO stays in the body so long. I thought you could just breath fresh air and clear it form your system quickly.

  You're correct. Breathing "fresh" air will drop the CO levels in your blood by half every few hours.

    A few hours is a lot slower than I'd imagined.
