Wow - they let you out qucikly ! Wishing you a smooth recovery now you're at home.
I'm in the UK too btw, I only just managed to get that added to my signature. I see you managed to get a heart shaped pillow from someone ! How lucky ! They gave me a rolled up towel in the hospital but when I got home I used a firm futon pillow which was really great for when sneezing or in the car between my chest and seat belt.
