I bought a Snoogle (I got it from Bed Bath & Beyond and used a 20% off coupon and a gift card!). I'm still getting used to it. Poor DH feels like the bed is being taken over.
I really like sleeping with my back against the Snoogle, but that way only lets me sleep on my left side. I was thinking about maybe getting a foam wedge or smaller Boppy Pregnancy Pillow to put on the opposite side of me, especially as the belly gets bigger -- it's slowly starting to feel awkward tossing and turning during the night with this belly.
