I use WBTB mostly. I was MILDing for a while but I've been kinda scatterbrained lately and never think to do it. But I mostly just do lots of RCs and do a WBTB. Another thing I did for a while was telling myself that it's easy to have LDs as long as I WBTB because the kind of sleep I get then is different and my mind is more awake. It was kinda sorta like auto-suggestion/positive thinking, but at the same time it's true. Now I don't really need to think about it.

I also do meditation and practice being very aware of myself, my surroundings and the sensations of things throughout the day.

Oh, and there's LDEILDs. You have to already have an LD to do it but this is amazing. When you notice yourself waking up from an LD you think to yourself, I am going to lie very still and fall back to sleep and go right into another LD. It works wonders, I've chained LDs together for 45+ minutes before. It's similar to a DEILD, just from a lucid. I've been meaning to try regular DEILDs but I've been procrastiniating like hell and making myself very busy and scatterbrained.
