The following PDF questionnaire will help you measure your general level of daytime sleepiness.

Answers are rated on a reliable scale called the Epworth Sleepiness Scale (ESS) - the same assessment tool used by sleep experts worldwide.

Please note that this scale should not be used to make your own diagnosis. It is intended as a tool to help you identify your own level of daytime sleepiness, which can be a symptom of a sleep disorder.
