How do you control late night eating!?

Im in the same position u r..soon going to college for fall..with so many papers to finish i stay up at times untill 12am. What i learned to do is drink something warm, like tea or apple cider...your going to drink it slow and forget about the food:) thats wht i do and it works..i dont want to eat bc i have a warm cup of tea to fill me up...Hope that works:)
