Congrats on the LDs! I experienced low-level lucidity just a few days ago. I mainly knew that I was dreaming from the fact that I was flying, but I didn't feel fully aware of the dream around me and had limited control. I gradually lost control until I was also falling on my face trying to fly again.

Anyway, I have to bits of advice for you. First, before you go to bed, decide what you want to to when you become lucid. That'll save you the time of trying to think of something to do or just letting the dream go where it wills (unless that's what you want to do). Secondly, when you notice that you're dreaming, make an effort to become fully emersed in it. Rub your hands together or against a wall to draw you more into the dream and away from waking up. Continue to remind yourself that you're lucid.

It'll just take experience and practice, but you'll get the hang of it in time Don't worry about it.
