Thanks for the advice everyone ^^

I'll start doing what's been suggested. One thing though - how many hours of sleep would I need to get for a higher chance of Lucid Dreaming? The trouble being, most of my personal time is spent late at night, I tend to only get about 5-6 hours sleep in an average night. And I'm not sure that this is enough, but extending it would lose me a lot of time I would normally have, and often for no reason should I fail to become Lucid. I guess this is the main problem to my failure.

Any ideas?
