Does anyone else get ridiculously stressed/nervous before a fight or comp?

If so, how do you deal with it/overcome it?

I'm not talking about an actual fear of being harmed or anything girly like that, but more 'performance anxiety', fear of failure that sort of thing.

I used to throw up before rugby matches and it's that sort of thing - basically a massive adrenaline spike that seems to sap most of my cardio.

I too suffer from this, can be fighting fit, great cardio sparring hard for hours, technically have no doubts but come comp time it all goes. Winyourmmafight.com is place where you can find more about how to relax before your fight or comp. The tips given there helped me a lot.

I like to fart, the louder the better.
