After that experiment, he slept for 13 hours straight and according to him, he was back to his normal self after that.
  • The Guinness World Record for the longest period without sleep is owned by Randy Gardner. He stayed awake for 11 days and 24 minutes. During the experiment, he was moody and showed signs of paranoia, suffered from hallucinations. He also had concentration and memory problems.
