I agree that night-time is the worst time for caving in to those late night carb cravings, but even though im generally not home until 8pm, and when i get home i still have to do housekeeping things like laundry, dishes, cleaning, shopping, phone parents, etc, if i have a hankering for carbs that arn't in my calorie allowance for the day, rest assured, it's only a matter of time before i chase them down and eat them.
It doesn't matter how busy i am, if all i can think about is food, i'll give in sooner or later. My thinking is that it is still only recently that you stopped eating above maintenance, and your body is probably missing the extra food. Give it a couple more weeks and it will get easier, not more enjoyable, but easier!
