I've read parts of her blog, but I recall it seeming like it required a lot of regular effort to maintain that schedule; almost as though she was still fighting polyphasic sleep every day.

Do you feel that it requires regular effort on your part to maintain that schedule?

Do you feel any differences mentally?

My experience was that is wasn't a physical struggle to stay on the schedule - it was a social one. The world does not do polyphasic and you have to defend your time. I eventually crashed out when I was supposed to come home ad sleep after work but my wife took me to dinner instead. Being up for 7 hours straight wiped me out for a day and it was too socially challenging to keep it up.
