Insomnia is the inability to fall asleep or remain asleep for an adequate length of time. It is commonplace for several people to suffer at least an occasional night of almost non-existent sleep. It is when the occasional night here and there becomes a pattern of several nights in a row that you are faced with a sleeping problem.
