Thanks for the responses.
I have tried that yoga technique before, among other things. It is pretty good for relaxing, but didn't put me to sleep!
I think perhaps I am more 'nocturnal' than a true insomniac. I can sleep fine during the day, its dropping off at night that I can't seem to do.

Another question I have, I heave heard about how our bodies natural timer can help/hinder lucid dreaming attempts.
For example, at a certain time of the night your body may be producing more of a certain chemical/brainwave that make it easier to WILD. (Not sure how true this is, its just something I've heard).

So, I was wondering if these changes in the mind will occur late at night regardless of whether I am asleep or not?
So I'm still up at 5am, is my brain acting as if I should be asleep, and therefore during the times when I am really asleep during the day will it be more difficult to get lucid?
