Have your snacks prepared when you begin a study session--don't wait till you get hungry and go rummaging for food. Avoid any snacks or drinks that will give you a rush of energy, because with every rush comes a crash in which all the information you studied is lost to an intense desire to sleep. Focus on "slow release" carbohydrates, which not only give you a steady stream of energy, but they also boost serotonin, a brain chemical that makes you feel good.
