I like to snack at night too. Cheese on toast is my personal favourite (naughty, naughty) but I don't think snacking is such a bad thing if your eating good snacks. And if you know you like to snack after dinner then plan a snack into your diet so your not just grabbing whatever's nearest. Some low fat yoghurt and a handful of dried fruit and nuts has lots of nutritious stuff in it and the yoghurt helps satisfy a bit of a sweet tooth too. If you don't want to waste calories or points, then rice crackers with salsa or hommus is good too and you can throw in some celery and carrot sticks and get an extra serving of vegies.
