i tried for zero sleep. Minimized it. Circles under eyes but I
   didn't care. But I get some now. Lots of nicotene and caffeine
   and staying up all night to avoid as much of the day as
   possible. Works well so far. Cut my sleep into two 3 hr periods
   so I _appear_ to be awake 24/7. Nobody knows how I do it tongue
