Your own pillows and a blanket! I'm super picky about my pillows and room mine own, as for the blanket, I took my have super blanket, hospitals are cold in my opinion, and I was thrilled to have the extra warmth and softness of my own blanket!
My surgeon encourages the use of it helps you get your fluid in! He even lets you while in the hospital directly post-op. I'm 1 year and 8 months out so far, without a straw, I don't get 1/2 the water amount in as when I do you a straw!
