Early morning awakenings can be very frustrating. Anxiety and depression are particularly common causes. Drugs and alcohol can also precipitate this. There are also other acquired behavioral disorders. Having a fairly rigid bedtime and wake time with no daytime naps is helpful. Bright light and screens should be avoided late at night but sunlight in the early morning is helpful at establishing better sleep. This is really a fairly complex problem and I would direct you to a free government website www.veterantraining.va.gov/insomnia. It is available to everyone not just veterans. Most people can be cured by behavioral interventions and sleeping pills at a young age would be best avoided. If you are anxious or depressed you should consult with your physician.
