Insomnia
Insomnia is characterized by an inability to sleep and/or to be incapable of remaining asleep for a reasonable period. Insomniacs typically complain of being unable to close their eyes or "rest their mind" for more than a few minutes at a time. Both organic and nonorganic insomnia constitute a sleep disorder. It is often caused by fear, stress, anxiety, medications, herbs or even caffeine. An overactive mind or physical pain may also be causes. Finding the underlying cause of insomnia is usually necessary to cure it.
