Has anyone managed to this, if even for a small period of time?

I think an ultimate goal for many would be to have a lucid dream every night, or somewhere close to that. But what about being lucid in every dream?

I know many claim that they can LD very, very often, so I want to hear what those people might have to say. In my experience, at my best I could acheive 2-3 lucids per night, but I never held onto this for more than a week or so. Plus, that still leaves 3-4 significant dreams per night in which I was not lucid.

So, is it possible or not?
