Other criteria include the following:

  • The sleep difficulty occurs at least 3 nights per week

  • The sleep difficulty is present for at least 3 months

  • The insomnia cannot be explained by and does not occur exclusively during the course of another sleep-wake disorder

  • The insomnia is not attributable to the physiologic effects of a drug of abuse or medication
