How to reset your sleep cycle in one night?

Oh, this is a hard one. To fix it in one night is... maybe not possible, eh? But you can try to start the change.

You must stay awake all the day. Do not take a nap. This part is very important. Stay busy. Then, go to bed at a good time, like 10pm. The next morning, wake up early. Go outside and get sun in your eyes. This tells your brain it is daytime. No coffee late in the day. And no phone light in bed. It is very hard but can help start the new cycle. Good luck.
