How strange.
I don't have that problem at all.
When I am playing well, I am playing well.
Now if I start making bad moves I tend to go take a break from it but definitely not if I am winning big and playing well.
How interesting.
I guess everyone plays differently, but to me poker is nothing like slots or video poker.
I instead encourage folks to play while you are playing well!!!
If you start making bad calls, or folds then it may be time to take a breather.
