[SNOWBALL138]

Here's one thing that helped me limit my tilt. I stopped feeling sorry for myself. Its really unhealthy to act as though the money you have in play is just supposed to grow. Having money in play means that you are comfortable with losing it, and other players have the absolute right to take your money. If they outplay you, or just get lucky, they are entitled to the pot. When I get angry about losing, some of it comes from feeling like other people don't have the right to take my money.
Another thing that helped me to limit the effects of tilt on my bankroll is something one of the posters here said. He said (paraphrasing) "Its just ridiculous that some people go broke because of steaming. Its a choice and completely a matter of self-discipline, and there's no excuse for this kind of personal weakness"
