Are there specific ways to keep awake the day after pulling an all nighter?

I checked for other questions like this and I still wanted to see if there were any other ways to keep awake. I have a mid term today and I stayed awake all night to go over everything. It wasn’t that bad about an hour ago, now I’m dragging. I can’t really keep moving because I won’t be able to get up from my seat except for about once an hour. I’ve drank so much caffine over the year, it has lost the inital energy boost it used to have. I really don’t have time to go and get food. Yes, I should be studying right now and not here, but I’ve got a moment to spare. Is there anything else that could at least keep me awake for the next 7 or 8 hours?
