I just finished puredoxyk's book Ubersleep. Awesome read - I highly recc it for anyone even vaguely thinking about polyphasic sleep (or just for general interest!).
Anyways - I am toying with the idea of trying an adaptation myself. It will be a few weeks of mulling/thinking about it at least - and I was wondering if I should 'learn to nap' in the meantime. I have never been a napper - and it strikes me that if I were able to nap during the daytime before trying polyphasic sleep it may make adaptation easier. Thoughts?
