if your planning on making a tutorial, it should include more things to try. It could be a lifestyle adjustment tutorial.

such as along with all of that you can add that you should take 100 mg of B6 before sleep, and stay up for 30 mins minimum for a WBTB

its just too little info for a tutorial, needs more research on what kind of lifestyle/routine will attract most LDs

maybe a lab experiment is called for?
