When I was in university I tried the polyphasic sleep technic for 5 weeks. Here are my findings: - The first 14 days are really difficult because the system must adapt and causes a severe lack of sleep. During this period, I would not trust myself to drive a car. - Do not drink coffee and alcohol because it completely destabilizes the system. - The vivid/lucid dreams where an incredible experience. - Not sleeping at the same hours as my girlfriend. - Time... so much time! It is also often the reason that people fail to polyphasic sleeping. Some people don't find anything to do and fall asleep watching television. Overall a very pleasant experience!
