Eating AFTER Dinner!!!

I don't know why it's so hard to close up the kitchen after we have dinner! I am terrible at snacking before bed. Since I started counting my calories, I've noticed it's hard for me to eat as much as I need to during the day. Then by night time, I feel like I'm super hungry. Most of the time I haven't even been near my calorie minimum. Then I tell myself that I have to get these calories in and I eat until I do.  I'm not exactly sure how I can fix this... I know the obvious choice is to eat more during the day and not eat after dinner, but if it was that easy I would have done it already! It's amazing how many bad habits I have that need to be changed.  I knew I had plenty of them, just didn't really open my eyes wide enough before to see.
