Is there any overwhelming reason to not eat in the evening? Does it cause you to have trouble sleeping, or increase acid reflux? Or is the problem more *what* you're eating, than the eating itself?
I always snack my way through the evening, with planned snacks that I enjoy and that add to my nutrition for the day. There are very few days that I don't have at least popcorn and a hot cocoa (made with skim milk and dutch-processed cocoa powder), and quite often I'll have either a frozen greek yogurt bar or a dish of yogurt with berries or almonds. My body requires the fibre hit from the popcorn, and I sleep much better when I have the protein from the milk in the cocoa and the yogurt.
Instead of driving yourself nuts trying to not eat, maybe try planning in some snacks for yourself that add to both your nutrition and your enjoyment. Check through your tracker records and see if there is a pattern to being somewhat low on one nutrient or another, and add in snacks that will bring those up.
Plan in 100g of carrots to nibble on while you're packing the kids' lunches, or some popcorn to crunch on while you're watching tv together. Create a relaxing evening ritual for yourself that includes a cup of herbal tea and some yogurt with berries - something that you have after the kids are in bed and you are sending a signal to your body that the day is done and it's time to sleep.
If you plan something that you really enjoy and look forward to, then it makes it much easier to resist the unplanned things that might wander by and tempt you.
I know this isn't exactly what you were asking, but I hope it gives you some ideas that might work for you!
