I usually try to get a really bad night's sleep the night before...an hour or two tops.

Then, about an hour or so prior to the occurance taking place, I convince myself to start feeling stomach cramps.

The most effective thing by far is the hyperventilating I do just after my event begins.

Other than that, no.

Complete surrender should not just come at moments in which one faces overwhelming odds, but in the calm when it seems one is personally in complete control of one's life.
