So I went to bed and slept for about 5 hours.
I have decided to back off to a less drastic schedule of a 4.5 hour core and 2 20-minute naps. When I am off work for Christmas break I will probably transition back but it's not going to work right now.
If you are considering trying a polyphasic sleep schedule I highly recommend reading as much as you can find on the subject and listening to how others have made it work, or not. I'm a little hard-headed sometimes though.
