Yes, I have, any physical activity that pushes you past your breaking point will cause it. I don't recommend this unless you are seriously trying to push yourself to the limit to compete in some type of contest. I was training for a marathon once and didn't want to stop because I knew if I did that I would lose the will to keep going, so as gross as it sounds, I would puke and keep going. It was horrible, honestly one of the worst experiences ever, but one that I'm glad that I pushed myself to do. You never know what you're capable until you cross that line.
