There's nothing intrinsically wrong with eating in the evening before bed. Many, many people, myself included, have lost plenty of weight while enjoying evening snacks. The important thing is your overall calorie shakedown, not when you eat each particular meal.
"Losing weight is easy; I've done it dozens of times."

Ultimate goal: Size 10 clothing.
