My advice!

Firstly, try not to sleep facing North or South Direction. 
If possible, change your sleeping position to East or West Direction. If really cannot, Sleep diagionally against North or South direction if you have no choice. Earth Magnetic field will affect your sleep especially when North and South directions have the greatest magnetic field strength.

Secondly, drink 1 cup of water before sleeping.
After waking up, drink another of water(Don’t brush your teeth first).
At first you will wake up in the middle of night to urinate. But after some time, you will not wake up any more to urinate.

Thirdly, before sleeping, tell your brain, you got to wake up tomorrow at what time.

Fourthly, subscribe to Spotify using family package. One good thing about Spotify, it really have a lot of sleepy music and compile them into few albums. See which sleep style you want. Light sleep, deep sleep or normal sleep style.
Play some sleepy music before sleeping, it will make you sleep.

I have never have any sleeping problem.

U know or don't know? How can ask people to change sleep position to West direction? 归西lor.
