I've long believed that free will is illusory. Empirical evidence includes studies that suggest that we may make decisions before we're actually aware of them (See Benjamin Libet: http://en.wikipedia.org/wiki/Benjamin_Libet) Your conscious mind is like a 6 year in the back seat with the toy steering wheel, pretending he's driving and making up stories about where he's taking us.
Despite that, I can't actually live my life as though I really have no free will. I tried it (briefly) as an experiment, and I merely sank into a sort of post hoc analysis of everything I did. "I was supposed to do that. That's what my unconscious made me do. Etc..." Indeed, I believe that free will is inseparable from identity to such an extent that even if we find unassailable proof that it's merely an illusion, we'll continue about our lives, "choosing," as if nothing ever happened.
