There are books about that stuff. Unless you are a pro or a cheat, going into a casino with a predetermined amount of money set in your mind is the only way to go. Like, when you are planning a trip to gamble, take a hundred bucks cash and say, when this is gone, so am I. If you work hard for your money, use that cash to buy a pair of running sneakers and get healthier. It's a better use of your hard earned dough.
