Can there be a way to change the habit of sleeping late at night?

Go to bed earlier.: 1. Keep a regular bedtime & wakening time (to include weekends). Get up the same time each day, regardless of what time you fell asleep. 2. Make a regular, relaxing bedtime routine. Relaxing rituals prior to bedtime many include a warm bath or shower, aroma therapy, reading, or listening to gentle music. 3. Sleep in a dark, quiet, cool room on comfortable mattress & pillows. >>>.
