Night Eating.How Do You Stop Doing This

Options
I am fine in the day and afternoon. However at night when I get home from work, it's a completely different story. I would really like to know how are you able to stop yourself from eating past 6:00 p.m. I have a son and husband at home who eats around the clock. They can afford to because they are skinny...I mean skinny! They are trying to put on weight and I am trying to knock off weight. Please can anyone help me in this area?
