In 1964 a young man, Randy Gardner of San Diego participated in the experiment and did not sleep for 11 days, the result of which was listed in the Guinness book of records. In the first two days he felt fatigue and irritability, and on the sixth day he began to show signs that foreshadow Alzheimer's disease, then hallucinations and paranoia, trembling hands, confused speech, forgetfulness.
Later this record was broken by 42-year-old Briton Tony Wright who stayed awake 11 days, but for a few hours longer than Randy Gardner. At this time he ate only fruits and vegetables, drinking herbal tea, played pool and kept a diary. In the Guinness book Tony never got because the deprivation category (deprivation) sleep was excluded from the book because of its destructiveness to one's health.
