In a video from YouTube channel In 59 Seconds, Richard Wiseman (http://www.amazon.com/59-Seconds-Change-Under-Minute/dp/0307474860) explains the main indicators of sleep deprivation, including needing several cups of coffee a day, or needing an alarm clock to wake up.
He also uses an animated "micro-sleeps" test to gauge if you are missing key details due to experiencing brief blackouts, which are caused by being sleepy.
Take the test to see if you are too tired for your own good.
