I've done this, and find that it works really poorly for me. If I'm not going to bed at roughly the same time and getting up at roughly the same time, I just stay muddled all day, even when I'm technically getting ~8 hours. If I stay on a schedule, I wake up without an alarm after 6-7 hours and I'm fully awake all day.
