Insomnia
Insomnia is a sleep disorder which causes an inability to sleep and/or inability to remain asleep for an entire night. Insomniacs typically complain of being unable to close their eyes or "rest their mind" for more than a few minutes at a time.
Insomnia can be caused by fear, stress, anxiety, medications, herbs, caffeine, depression, or other mental conditions and sometimes occurs for no apparent reason. An overactive mind or physical pain may also be causes. Finding the underlying cause of insomnia is usually necessary to cure the disorder.
