I agree with snumbers, but the most helpful thing I could think of at this point is training yourself to do reality checks. So far's I remember there're some in the tutorials section of the site, but what they mostly comprise of is just embedding in yourself the reflex to do a check whenever things seem in even the smallest way out of place.

You may feel silly whilst awake, but I don't think there is a better way of proving to yourself that you're dreaming, and thus hitting a very lucid state.
