No caffeine for 6 hrs ; no alcohol or tobacco w/i 2 hrs of sleep. Keep dinner moderate sized ; finish at least 2 to 3 hrs before sleep.

See below: Establish time when you would like to go to bed. Create a bed time routine: warm showers, room on a slightly cooler side. Learn relaxation exercises to help put your body in a "i'm sleeeeeepy mode" :). Don't use your bedroom as your office. Try to avoid afternoon naps, no caffeine after 3-4 pm. Use your bed for sleep and sex only. Our body likes schedules and routines. Remember that:).
