How can i regulate my sleeping habits in 10days (before school)?

Sleep Hygiene: Establish time when you would like to go to bed. Create a bed time routine: warm showers, room should be on a slightly cooler side; no tv, no computer. Learn relaxation exercises to help put your body in a "i'm sleeepy mode" :). Don't use your bedroom as your office. Our body likes schedules and routines. Remember that:) not sure about 10 days deadline as we are all different. Consistency is key.
