But did you really think there were 10 alternatives to sleeping?
Why is it you're so desperately trying to stay awake?
You need to sleep.
It's your chance to recover both mentally and physically from today so that you can operate more effectively tomorrow. The myth that sleeping less will allow you to improve results in other areas of life is a by-product of a culture obsessed with productivity.
You don't need to sleep less.
You need to do less of the other things that are keeping you awake.
Put down your coffee.
Go to bed.
