I participated in a sleep deprivation study conducted by the U.S. military. I didn't sleep for 88 hours. AMA!
I recently participated in a sleep deprivation study at a U.S. military research center. The study was conducted in a dorm-like setting, with separate rooms for each participant (there were four of us) connected to a common room that had a television and kitchen. Our private rooms were used for conducting numerous tests gauging memory, motor skills, et cetera and so forth. We cycled through these tests over and over again -- with only short breaks in between -- for the entire duration of the study. We were not allowed to use caffeine or any other substances, although we were provided with food whenever we wanted it.
After about 65-70 hours of no sleep I began to hallucinate.
Sleep deprivation is definitely torture. Anyone who says otherwise is an asshole. Anyway ... Ask Me Anything!
EDIT: trying to answer questions as quickly as possible! Thanks for your interest.
EDIT #2: This question is popping up a lot so I'll just answer it here: I was paid roughly $2,000 to participate.
EDIT #3: Thanks for the front page vote-up, guys! And now a Predator Drone will murder me for revealing U.S. Sleep Deprivation Secrets in 3, 2, 1.....
