There could be several causes of your sleep disturbance, and I recommend that you make an appointment with your primary care doctor
to discuss this issue.
The most common cause of insomnia
, or sleep disturbance, is probably stress and other psychological or emotional factors. If you are currently undergoing a lot of stress or if there have been major changes in your life, these factors could cause changes in your sleep. You can talk to your primary care doctor about this and, in addition to thinking about ways to reduce the stress in your life, you may want to talk to a counselor or therapist
Another major cause of trouble sleeping is the ingestion of caffeine or other stimulants. You may want to try stopping all caffeine intake, especially in the afternoons and evenings and see if that makes a difference.
Similarly, alcohol severely disrupts sleep. Although some people find that alcohol makes them drowsy and helps them get to sleep, it prevents good deep sleep later in the night, resulting in awakening and feeling fatigued the following morning.
Start by talking to your doctor. They will help you determine if further workup of this problem is needed if a cause cannot easily be identified.
