I was thinking about reality checks when an idea occurred to me: Tattooing "Am I dreaming"(or whatever variation) somewhere on your body that is visible to you. Yes, a little extreme. I would suppose that lucid dreams would be very abundant in the first couple of weeks of the tattooing, which could be very helpful in learning the best ways for yourself of attaining lucidity. After that, the tattoo would merely be part of your identity and appear in your dreams as often as your limbs do; seeing this question on your body would most likely always bring up the question in your mind, leading to awareness.

I don't know if anyone would be willing to do this, but if so, you can rest assure that any doubts to whether it would work would be smothered to death by the hype surrounding such a commitment.
