Has it really been a year already since you stopped it, Steve? Wow...time flies. (Seeing Erin's Anniversary post makes me wonder if you stopped as an anniversary present to her last year?
)
I was riveted to the polyphasic sleep posts as well. Not that I'd ever be interested in doing it, it was just fascinating. Also, my 18 year old daughter has sleep habits much like CarrieB's. It seems to work well for her.
