Polyphasic Sleep: The Great Hiatus

Summer break began yesterday. I will be home most of the summer -- that, and travelling with the family (currently in Los Angeles). Ergo, I am readapting to the monophasic life. I've had some experience doing so, certainly, over spring break, but not for any significant duration. This should be quite an adjustment.
Of course, not enough time has elapsed, so I don't know exactly how it will go. Thus far, I seem to retain my ability to fall asleep very quickly in pretty much any situation. I find myself getting mildly sleepy in the afternoon, but that goes away. I'm having a bit of trouble sleeping through the night; I wake up at odd hours (at multiples of 90 minutes, no surprise there), but I can go back to sleep. It's still a bit surreal, though, to get out of bed and find that it's light out.

P.S. Five nerd points if you get the title reference.
