Just like your bed time, a Pre-bed time should be spent in a relaxing place and situation (mine is on the right side of my couch, checking out Pinterest), but with a time limit. When it’s time to go to bed, leave your phone there and go to your ‘real’ bed room.
1- get less amount of sleep the night before, force your self to wake up early.
2- do a good amount of physical activity such as exercising or house deep cleaning.
3- put your phone in the living room before sleeping and use old style alarm.
4- it might seems funny but try to count it might help sometimes.
