I've Gained Over 50lbs Over The Last 2 Years. One

I've gained over 50lbs over the last 2 years. One of my problems is that I tend to eat right before bed . If I don't eat then , I wake up in the middle of the night to snack on something. Is there something I can eat right before bed that will satisfy me without consuming a lot of calories that will keep me asleep through the night.
