What is the best way to keep yourself awake for 20 hours?

20 hours really isn't all that bad, provided that you start your 20 hour day well rested. 20 hours represents losing a single half night of sleep, which while uncomfortable, is commonly done all the time. Here are some tips: Make sure you are healthy, hydrated, well rested and in good shape to start with.

The better condition you are in, the easier it will be for you to power through a long day when the need arises. Remember to eat throughout the day so that your body has plenty of fuel for energy. Coffee, energy drinks and caffeinated beverages can give you a boost if you really need it, but don't take them too late in the day or you won't be able to fall asleep when you finally do get home.

Rest breaks can really help you recharge and power through the long day. If you can take your mind of the task at hand for 10 minutes or so, you will feel more refreshed and be able to get more done. If you can exercise or doing something physically active, it might help make you more alert.

Bright lighting and upbeat music can also give you a lift and help you resist the urge to nod off when you are really feeling run down. Chewing mint gum or sucking on a mint candy can also give you a boost, almost like coffee. If your goal is to consistently stay awake for 20hrs, I wouldn't suggest it.

Over time you will get run down and sooner or later you will crash hard.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
