It takes almost 1 hour to make my brain tired enough to sleep. also, i cannot sleep more than 7 hours. what can i do?

Use excellent sleep: Hygiene. 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 may include a warm bath or shower, aromatherapy, reading, or listening to gentle music. 3. Sleep in a dark, quiet, cool room on comfortable mattress & pillows. >>.
