Ubersleep: Nap-Based Sleep Schedules and the Polyphasic Lifestyle - Second Edition

Polyphasic sleep: Trading the length of one nightly sleep for frequent shorter naps, resulting in less (sometimes much less) sleep-time overall, and many other interesting changes. This is the Second Edition of the UberSleep Book -- the definitive work on polyphasic sleep schedules as a lifestyle, written by one of the first long-term Ubersleepers and a polyphaser of almost a decade. Extensively updated, the Second Edition contains all the original material defining polyphasic sleep schedules and giving detailed advice on adapting to polyphasic sleep, plus many new sections and expansions on the many facets of living on a polyphasic sleep-schedule long-term.
