Sleep Deprivation Problems?

Research suggests that as sleep deprivation increases, attentional failures increase. Practically speaking, have you gone without sleep for extended periods of time? What effects have you experienced as a result?

Steven W. Lockley, et al (2004) concluded "Eliminating interns’ extended work shifts in an intensive care unit significantly increased sleep and decreased attentional failures during night work hours."

Comments? Your experiences?

Chronic restriction of sleep to 6 hours or less per night produced cognitive performance deficits concludes Hans P.A. Van Dongen, Greg Maislin, Janet M. Mullington, and David F. Dinges (2003) in The Cumulative Cost of Additional Wakefulness: Dose-Response Effects on Neurobehavioral Functions and Sleep Physiology From Chronic Sleep Restriction and Total Sleep Deprivation, Sleep, Volume 26, Issue 2, 1 March 2003, Pages 117–126. This makes me wonder why students cram for exams?

Cari Gillen-O’Neel, Virginia W. Huynh, and Andrew J. Fuligni (2013) in To Study or to Sleep? The Academic Costs of Extra Studying at the Expense of Sleep, Child Development, Volume 84, Issue 1, pp 133–142, concluded: "Results suggest that regardless of how much a student generally studies each day, if that student sacrifices sleep time to study more than usual, he or she will have more trouble understanding material taught in class and be more likely to struggle on an assignment or test the following day." But I will still cram for exams.
