Drink 2-3 glass water before going to sleep and you have to wake up around 4-5 am
If this doesn't work or suitable then set an alarm in mobile and for the 1-2 month go for morning walk just after you wake up. Otherwise, maximum persons including me, make alarm turn off and again go to sleep and wake up after 1 or 2 hours.
Alternatively, you can go Gym or play cricket or other sports in the morning.
For alarm you can set your favourite song or any very energetic song that make force you to wake up and listen to the music, it will make your body very active.
You can also set some audio notes created by as an alarm.
Take help of any family member or friend to make you wake up. Tell them they keep trying until you get out from the bed.
