The main reason for sleep is to allow your mind to process all the happenings of the day. Your body should be pretty fine after a full day of being awake, so long as you can get your mind right. If you don't want to take a nap then try meditating for a little while. As a form of 'conscious' sleep, it's more time efficient than a nap. I meditate when I run so that's what I'd do, but that's not for everyone. :)
 
Haha! Not quite... I have a set running track and so my body becomes kind of automated as my mind does it's thang. Thankfully my mind is tiny like a newt so it doesn't take long. Five kilometres should do it. :p
 
Nice! I'm prone to tripping, so i'd probably break my legs if i do that :p.
 
The ONLY thing that will help your body is sleep. As much as possible. Saying 30 min is better than 3 hrs is bogus IMO. Yes, you might be in a deeper sleep phase after 3 hrs - which is exactly what your body needs - and so the first 10 minutes after waking up might be slightly groggier than after the light sleep you get after 30 min. But at least you did give your body some of the deep sleep it really needs.
That's not exactly true. 3 hours is better than 30 minutes, but but because of the way the sleep cycle works, 30 minutes is better than an hour or 1.5 hours.

It's too late for the advise now, but I feel like typing anywaY. :D
- If you use an energy drink, drink a sugar-free one. The massive amounts of sugar will give you energy for a few minutes, but you'll crash afterward. At the same time, eat something. Not candy or chocolate, for the same reason. Get some protein, some complex carbohydrate (fruit, whole wheat bread, beans, whatever), some vegetables. Drink LOTS of water. You'll be dehydrated, and caffeine makes you even more dehydrated.
