I'm 25 but a kid inside so I brought a small soft blanket I love and a stuffed animal.

Don't forget a pillow for in the car so you can hold it against your stomach on the way home.

I wish I had brought my ipod and headphones.

I wish I had boughta wedge pillow for at home.

I brought paper and a pencil just in case.

Also, I brought my camera so someone could take my pic for my scrapbook.

The list of things to bring in my WLS program book from my hospital says:
list of all your meds (do not bring meds)
copy of living will or power of attorney
robe and slippers
chapstick ( i myself love love LOVE carmex in the little pot with the yellow lid - lifesaver)
loose fitting clothes to go home in (bra and underwear..ha ha...yeah right, lol)
c-pap or bi-pap machine
glasses
reading material (essential as my stay was supposed to be same day and I was overnight)
toothbrush/tooth paste (didnt use em)
clean undergarments
a container for dentures, contacts, etc
comb/brush (or hairband)
toiletries like make-up and deodorant

I was kept overnight and was at the hospital for about a day and a half because of a slight fever but I was better off there in the movable hospital bed than at home on the love seat as I couldnt sleep comfortable in bed for about a week.
