Symptoms of Insomnia

You may have insomnia if you:

  • Have difficulty falling asleep—Normally, it should take no more than about 30 minutes to fall asleep once in bed.
  • Have difficulty staying asleep—You wake up frequently during the night with difficulty going back to sleep.
  • Wake up too early—Waking early in the morning may be normal for “early risers.” It could be a problem, though, if this is not normal for you or if you are not getting the sleep you need.
  • Feel nonrefreshed after sleep and tired during the day—This may indicate that you are waking up during the night or not getting an adequate total number of hours of sleep.
  • Feel restless or anxious as bedtime approaches—You may be anticipating insomnia and worrying about it.
  • Other symptoms may include:
    • Fatigue or sleepiness during the day
    • Difficulty concentrating
    • Performance at work or school is suffering
    • Moodiness; feeling irritable
    • Lack of energy or motivation
    • Feeling preoccupied with thoughts of sleep
