Is it better to not sleep or get very little sleep?

Answer 1

It depends, if say you're going to bed during the night, being unable to sleep, and watching films until five in the morning and you have to get up to go to work or school at six it'll be pretty hard to get up. On the other hand it might be better to have an hour sleep at least, it does make a difference during the day and will give you a little more energy to function.
