Well, it's been 3 1/2 years since my original experiment, and I still get several emails a week asking me one common question: "Are you still doing a polyphasic sleep schedule?" I usually point people to my other blog where I made an entry about how things are going these days. You can read that entry here:

The last "Polyphasic Sleep Experiment" blog entry

I still love to hear from people who have suceeded or are thinking of trying it, so feel free to drop me an email if you want.
