First off, to DV!

Cool, you have had lucids before! I would suggest visiting the tutorials section to find a technique that fits you. Pick one and stick with it. It sounds like you have a dream journal, which is good, and is a big step towards lucidity. Remember, if you don't succeed, don't give up. Lucid dreaming takes practice and patience. If you keep up with your RCs and awareness, you shall soon achieve another LD.
