pack light, you'll sleep most of the time-the rest you'll be walking or won't really care.
i took the following:
chapstick (a MUST)
brush, hair tie
cell phone, charger, head phones
eye mask and ear plugs (for peace and quite in the day time)
chonies, socks, robe and slippers
magazine
i knew the hospital would have the following for me to use:
a gown
toothbrush and toothpaste
soap, lotion, washcloth
extra pillows and blankets
i wore comfy loose clothes in, same clothes out (with clean chonies) :]
walk as much as possible, use your chapstick, and keep your mouth wet.
at home-always have Water nearby, Protein drinks at the ready, and plenty of options for liquids/clears such as sf Jello, pudding, popsicles and broth. i used my recliner a lot because it was easier than the bed.
