Make sure the room you sleep has minimal light Make sure u fix up a definite wake up time irrespective of the time you sleep and avoid sleeping in the afternoon.this ensures that the sleep is accumulated and you'll automatically sleep after 2 or 3 days of following the same. Sometimes a warm bath, or a glass of warm milk will be soothing before you sleep. Try writing out the thoughts in case you are not able to sleep to allow urself to think about them the next day.
