I’m glad to hear that you’re sleeping better! Since I can only really speak to my experience I never know if my suggestions are actually useful for others, so I’m glad to hear that something I said might have been helpful.
When reading through the thread again, I noticed this statement. Although I relate in being confident in my lucidity (when I question if I’m dreaming in a dream, it’s often enough to give me lucidity, although I have talked myself out of lucidity before 
) I would be cautious about being confident about WL-that you know you’re awake.
I think being a DILDer (MILD is a type of DILD) it has been helpful for me to adopt the idea that I could always be dreaming. I think that philosophy has helped me develop a more discerning mindset? Like shifting my default mind from “This isn’t a dream” (a WL attitude) to “This could be a dream” (a reality questioning attitude). Our mindsets carry over into our dreams. If you’re always so sure you’re awake in WL, that could be holding you back from more lucids because you’re assuming you’re experiencing WL in your dreams (otherwise, you would be lucid).
I’m not sure what I’m exactly trying to articulate, but maybe something like developing a lucid mindset?
