I have tried this a few times because I was very curious. I listened to the lucid dream dose many times. I found that I had a much better chance to have a dream that I would remember if I listened to it as I was falling asleep. I don't know if it works because I think it works, or if it works because its so boring listening to a 30 minute dose that it puts me to sleep right away.
Who knows, I say its worth a try. If you want to do it right, relax for a while before you listen, then listen in a dark completely silent room without any interruptions.
