I do not normally snack on anything late at night. My last meal is usually somewhere between 7 p.m. and 7:30 p.m., and it is always a light snack. I have never believed in eating late at night. Furthermore, my bedtime is fairly early, no later than 9:30 p.m. most nights. I have heard some people say that they would get up sometimes in the middle of the night to snack on something. I have only gotten up in the night to drink a glass of water if I was feeling thirsty.
The only occasion that I would eat past midnight is on New Year's Eve since I like to watch out the old year, so before going to bed on that night I may probably just take a glass of juice with some crackers or bread with either cheese, peanut butter or jam. If I am dining out that night, which I have not done in a while, then it would be a full meal.
