So if you find yourself tilting, try nitting up a lot. This isn't necessarily the best way to play poker generally, but it is a good way of fighting tilt because you will avoid a lot of the situations where you end up throwing your money into negative EV plays. When you get off tilt, you can loosen up your game a bit again.
