I agree with AnagrammadiCodeina that postponing sleep is not advisable. It causes more problems in the long run than it is worth. However if you insist that it is needed to reach deadlines, things that keep you awake are caffeinated foods and beverages like coffee, green/black tea, and energy drinks. Or foods high in sugar, like candy and chocolate.
