Hi, I was bypassed 8 months ago, best thing I ever did. I took the usual toiletries, loose pjs, Vaseline for lips, hair bobble, baby wipes, slippers, comfy trousers for travelling home, cushion to hold on stomach for travelling home too. I took a book which I didn't read and phone and phone charger. I was given peppermint tea which helped with wind pain afterward but try to get up and walk about ASAP to help move that wind. Good luck, you'll do great!
