Try light therapy

Insomnia and other sleep problems are treated using light therapy. The goal is to re-set your body clock so that you are awake during the day and sleepy at night. If you have difficulties getting up in the morning, light therapy might help. If you have a habit of waking up too early in the morning, light therapy in the evening may be beneficial.

You'll sit 1-2 feet away from a light therapy box, which emits strong light while getting light therapy. Although the light is artificial, your body will perceive it as natural sunlight. The light tells your body to cease producing melatonin, a "sleep hormone." If you use light therapy on a regular basis and follow your doctor's advice, you might be able to adjust your sleep schedule to match your requirements.
