Here is a very good reply to the arcitle from Puredoxyk:

Puredoxyk is one of the two (back then) college girls, who lived on the Uberman Sleep Schedule (and gave it its name) back in 2000. She is also author of the original E2 node about Uberman SS. http://everything2.com/node/892542

There is great discussion on the Google Polyphasic Group about this [Dr. Wozniak's] article: http://groups.google.com/group/polyphasic/browse_thread/thre...

Here is my quick summary:

1. There is not enough scientific data to backup either side (for/against polyphasic);

2. Dr. Wozniak has his own agenda - he advocates so called "free-running sleep";

3. Some of the "facts" [mentioned in Dr. Wonziak's article] are in contradiction with experiences of people who tried polyphasic sleep, like Puredoxyk ( http://www.puredoxyk.com ) or Steve Pavlina ( http://www.stevepavlina.com/blog/2005/10/polyphasic-sleep/ )
