It depends on the amount won. If it exceeds my initial balance two times and more, I stop right away. I may come back later, even the same day, but when I win big, the first thing that comes to mind is to quit for the moment. It's perfectly okay, when you play games against the house, but I suspect that it can annoy other players at the table when you play poker cash games, and I'm really sorry about that, but that's how it is, I completely lose interest for the game after a big win.
