Insomnia

Insomnia is difficulty getting to sleep or staying asleep for long enough to feel refreshed the next morning. An insomniac may also experience:

Waking in the night (most common in older people)
No feeling refreshed after sleep and not being able to function normally during the day, feeling irritable and tired and finding it difficult to concentrate.
Waking when you have been disturbed from sleep by pain or noise
Waking early in the morning

Nearly everyone has problems sleeping at some point in their life and it is thought that a third of people in the UK have bouts of insomnia. Insomnia appears to be more common in women and more likely to occur with age.
