I would say don't overpack. I was sent home the same day after my vsg, and for the rny revision, I went home the next morning, about 24 hrs after being admitted. Basically slept till my release. What I found necessary was a very loose outfit that you can slip over your head, comfortable shoes, your cell phone, necessary ID items and a small pillow for bumps in the road for your ride trip go home is really all I needed.
