For the last two nights, I’ve slept on my back. This despite being a side-sleeper for pretty much my whole life. I have a certain way of tucking the pillow into the side of my neck, settling in, and nestling my back up to a pillow or another body. But my shoulders suffer, and the asymmetry sets me up for all kinds of misalignments. I’ve tried re-training myself many times, but I let myself go back to what’s comfortable when sleep has eluded me. This time, I think I’m on track to finally interrupt this persistent habit.
