that is the same as with any abrupt sleep pattern change - try having the old stay-up-to-4 sleep schedule and immediately switching to a midnight-to-8 system (as referenced in http://xkcd.com/361/ ). Getting up at 8 after 4 hours sleep will suck, and you wont be able to fall asleep until 2 or 3. It takes a week or two to switch, so switching to a 6-day schedule should take, i'd guess, somewhere on the order of a month
