_Sky's suggestions cover (IMHO) two really important points:

a) Eating healthy stuff rather than crap
b) Not upsetting yourself if you do eat something unhealthy - deprivation very often only leads to more binging

If it wasn't 'emotional' eating I'd suggest stuff like no carbs after 4pm, protein shakes to fill the gap, low GI foods to help shift that last bit of weight. But I am sure you are doing that already

good luck
