Has anyone switched from being a night owl to being a morning person?

My most productive hours are 12AM-6AM. I find myself falling into this schedule despite trying to change it multiple times. Before I throw in the towel and accept my fate as a nocturnal creature, has anyone successfully switched from being a night owl to a being on a regular schedule or (gasp) even being a morning person?
