New Here and surg tomorrow

Hello,  My surgery was orig scheduled for RNY on 09/01 but my Dr's office called late Friday afternoon and rescheduled it for 08/23, Tomorrow!!  I have to be at the hosp at 5:30am.  I'm a little nervous but so very excited!  Any suggestion on what should I take with me to the hospital?  I've only been hospitalized three times in my life and all were for c-sections...gonna be a bit strange not having a new baby with me LOL.
