Have you ever tried to coax your physiology into requiring less sleep?

There is so much to do, things I want to do, but sometimes it’s difficult not to sleep a lot. Especially in the winter! My lifestyle allows oversleeping now, but I’d rather be awake, energetic, productive. Has anyone ever tried to form a long-term habit of reducing sleeping time by at least an hour (and, preferably, more)? Can it work?
