Normally, when I sleep, I sleep on my side, with my legs pulled up and bent. I heard that it’s better for your back if you bend your knees like that and started sleeping that way.
But now that I’ve lost so much weight, when I lie down like that, my knee bones bump up against each other, and my legs don’t fit together well. I’ve had to start sleeping with a pillow between my legs in order to be comfortable. Just another thing to get used to about my new body.
