Yikes! I'd suggest healthy carbs like apples for energy (instead of sugary snacks), and some protein or fiber earlier in the day to keep you full, so you're not starving by the time 11 rolls around. My go-to study snack is a Fiber-One bar... only 90 cals, but it still has a bit of a sugar kick when you nee a boost.

Happy studying! Best of luck on your finals!

It may be a little late at this point, but I'd suggest not having them in the house at all. That's what I do. Studying always makes me a lot hungrier and I find myself snacking more frequently whether it be from the stress or actual use of "brain power." So, instead I keep stuff around for different cravings.

salty: Multigrain crackers, cheez-its, microwave popcorn, pickles, even deli meat.
sweet: apples, pears any fruit I can get a hold of, dry cereal (usually one of the cheerio variations, corn flakes, shredded wheats-whatever you like best and if it's loaded with sugar, just try to eat by the serving size to be mindful of the calories-though with finals, calorie counting can be tougher) peanut butter, dark chocolate (not actual candy bars though, way too tempting for me), nature valley bars, just break them up to portion them if you need to since it's about 190 for 2 bars, unless you're eating the protein ones, then 1 bar-190.

Good luck with your finals.

i spent some time on off-shore rigs and ships before i decided to come back to school, they were'nt really buffet style. the best thing i found to not be starving 20 minutes after i ate, was loading up on rice, or grits or oatmeal and vegetables, something filling. or take a little protein powder and mix a shake before you engorge. you can use a sheet of paper as a funnel into any bottle. if your still wanting to snack, swap the oreos for something with protein like almonds or something that goes with hummus

I have to agree with the two posts above me, During finals I had protien powder and it helped, the energy drinks give you an energy kick and a sugar craving, i just did coffee with Stok expresso shots (from 7-11) and tried to hydrate, sometimes snacking is a distraction from just knocking out the things you should be doing, i lost about 900 cal getting work done but the things wrapped up quicker and then i spent 3days sleeping and getting back on track.
