Insomnia is a persistent disorder that can make it hard to fall asleep, hard to stay asleep or both, despite the opportunity for adequate sleep. With insomnia, you usually awaken feeling unrefreshed, which takes a toll on your ability to function during the day. Insomnia can sap not only your energy level and mood but also your health, work performance and quality of life.  Insomnia symptoms may include: difficulty falling asleep at night, awakening during the night, awakening too early, not feeling well rested after a night’s sleep, daytime tiredness or sleepiness, irritability, depression or anxiety, difficulty paying attention, focusing on tasks or remembering, increased errors or accidents, tension headaches, distress in the stomach and intestines (gastrointestinal tract) and ongoing worries about sleep.
