Sometimes I'll play and win a tourney from PokerOwned. Then, if I take the winnings on the site I won on, and play a sit-n-go, or a small tourney, I usually place or win again. But if I go into a mode where I stay up half the night and keep playing, I always wind up pressing the cards and losing. You shouldn't play until you lose. You should win and stop till you're rested and ready to focus properly again.
