I attained lucidity the second night I began trying. Three times that night, I became lucid, but woke up immediately from the excitement each time. About a week later I Had another LD in which I didn't wake up right away.

I'm still new at this and so far they haven't been very long, but in each dream I've gotten progressively better and remaining calm and gaining control. I haven't had enough of them to give an accurate average of how often they occur, however.

That being said, I've been an extremely vivid dreamer all of my life with naturally excellent dream recall and a habit of keeping a dream journal. I consider all these things integral to the immediate success I've had with lucid dreaming.
