I can't find a good sleeping position to start WILDing
I fall asleep most naturally on my side, kind of curled up. When my alarm sounds for WBTB, I try to start when I'm lying on my back because I read that that's the easiest position for WILD. But my body gets uncomfortable very quickly, and if I'm not very tired, I'll be lying on my back for a long time. A lot of times I end up almost involuntarily rolling on my side because the relief is immediate.
But every time I try on my side, it's hard to control my breathing, and worst of all, I end up being so comfortable I slip into regular sleep with only a half-hearted attempt at WILD. I also haven't felt SP when I'm on my side.
So either I can't do the dream part, or I can't do the lucid part. What do I do?
