Has anyone tried or had experience with polyphasic sleep? My interests lie in getting by with less sleep each night, something I cannot do on a normal sleep routine. At one point I gave serious consideration to setting up a routine for this. The problem is that I absolutely require 6+ hours of normal sleep to function close to normal capacity. Even at 6 hours I can feel my mind slower and my normal tact is usually gone. So a transition into a sleep routine as such would be monumentally challenging for me in my everyday work environment.
