I hear ya!
Breaking the habit of night-time eating is really hard. I budget a bowl of cereal for night out of my food for the day and try to eat it very slowing and enjoy it. I try to keep my hands busy too. Do you knit or crochet? Anything that doesn't go well with eating can help. Even a hot bath can help.
Also, a good stash of very low cal snacks (like raw veggies, lo cal dressing or dip) can help if you just really need to eat.
Hang in there! You can lose even if you eat at night, you just have to plan it and work to change the habit.
