There's the Astarion/cazador scene depending on what routes you take in act 3 but I don't want to spoil anything. It's pretty brutal.

I use the belly sleep pillow from Amazon and it's the best I've found after trying all sorts. It reminds me of one of those thin Oreos, which... When you sleep on your stomach, thinness apparently works wonders. I'm happy not to be suffocated by pillow fluff and it's very rare for me to get a crick in my neck anymore
