I think everyone has encounter the same experience as you. Including me, I can not avoid that even those money that's supposed to be for food and other expenses to our home is lost I spent all of it. Because I'm tempted to buy things that should not be bought and eventually I understand my mistakes but it's too late for me. I don't have enough courage to prevent this kind of habitual.  it's just a money we can still earn it anytime. But those satisfaction that we feel is not worth the money. You only live once , so enjoy it while you are here in this world....
