Staying away, is not so easy as the most people are saying but I must say its pretty easy if you can control yourself and stay away from it.
Let people social control you, they can really help you with it, I have no doubts about that, family will almost help you with everything in my opinion.
It makes sense asking for family help basically would make us scolded loudly and we will think twice to do gamble again.
But how if someone don't want their family knows his bad habit, and prefer to hide it from everyone?
I guess a hard addicted to gamble causing lost so much money needed a professional help, nothing else.
