Sleeping Difficulty

Insomnia or sleeplessness is a common sleep disorder characterized by insufficient sleep. It could be due to difficulty in falling asleep, maintaining the sleep or both. Insomnia is not always a disease by itself. It is usually a symptom associated with other disease conditions that cause sleep disturbance.
