Welcome to the forum!

I'm just going to add to great suggestions above.

Since it seems like you have great recall when you get full night sleep, you could start by focusing on those nights. In our busy lifestyle, goal of having a lucid as frequently as we used to may not be very realistic.

You didn't say how did you used to get your lucids. Are you a natural LDer, or did you practice a method? In any case, you could read up on DILDs, WILDs and DEILDs. Then make the day when you have time to sleep in a special day. Think about LDs, read your dream journal or other members entries, make a plan of what you want to do in a lucid to let your mind know what you want it to do. Get excited about it and set your intent of having a lucid that night.
