[Mr. Curious]

Congratulations on stepping up and admitting your problem!

That is the first and hardest step.

Now you just need to spend some time trying to remember the very first time this happened. Was it when you first noticed it, or has it been there all along and something specific (like a bad beat, etc.) brought it to the forefront? Are exterior factors affecting your play?

Don't try to jump back into the level where you left. Play in the micros for a while and when you next notice that you are tilting, stop playing and think back to why it happened. Use the hand histories if necessary and you will figure it out.

Good luck!
