Looks a lot like figure 4 in that article, but with my arms wrapped around a pillow. The arms hold up the head, and the neck isn't rotated so much that it hurts. There's usually a little twist at the hips, and my legs are kinda jackknifed as in the second figure 2 picture (I just noticed the caption points out how "the penis is protected from insects", ha ha). Very comfortable, though my ribs will get a little sore after a while, so I rotate with a side sleeping position throughout the night.
