Commonly I terminates gambling after five unsuccessful efforts, take my drinks and back to home ( when in gambling shop) or go to bed (when on-line at home).

It's not a good idea to switch to alcoholic drinks when you've lost money in a casino. Still, there is a much greater temptation to break away and go play again. This has happened to me more than once. Yes, now I can afford to grab some beer and play online. Still, it’s much better than getting completely drunk with friends who don’t know the limits in this matter.
