I manage to play okay, build up a good roll, then the invetiable downwing comes - but I can't stop it - this has happened time and time through my poker career - I clearly have tilt issues, but have no idea what to do about it, or how to counter it?

Are there any videos recommended or advice of how to break the cycle? I'm so frustrated that I've had to withdraw my bankroll as I genuinely believe if I play that it will all go sooner rather than later.

As you can tell from my graph 25NL - I should not drop 14BI in 1500 hands!

So yeah - any advice, articles, videos, general tips would be greatfully recieved.
