I have carnation instant breakfast drinks (well a drink) at night if I find I'm craving stuff. I don't really deny myself food if I'm hungry. That being said, the breakfast drink with nonfat milk is about 220 calories (4pp for WW, which is my plan of action), and has a good bit of carbs. I find it filling, and after a while I actually stopped getting hungry around bedtime. Eating right before bed also didn't seem to have an effect on my weight loss.
Everyone is different, finding something within plan that I could eat and feel full on worked for me, I know others that keep out of the kitchen entirely past a certain time. Experiment with some stuff and find what works for you
