I think many of us use food to sedate, not only at night, but during the day also. So, with me, it's a balancing act of looking what's underneath the craving and truly feeding myself. An egg yolk in the middle of the night always puts me back to sleep. But, for me, eating and then going to sleep doesn't allow complete digestion. Everyone is different. So, more and more I have learned to self sooth myself, thus avoiding the addiction that eating maintains. Interestingly, most of the times I wake up after self soothing, I am not really hungry at all. But in general, I would look to fats, rather than sugars, or bread, to put you back to sleep.
