Everyone is different, some stay one night, others stay a few days then go home or to a rehab facility. IMHO, I think at least one night is safer to make sure you're alert, walking at least to the restroom, your pain meds are working and you aren't suffering any after effects from the surgery. Many people wake from surgery and feel fine so think they sailed through with no aftereffects, then the first night or second day hits like a hammer. My advice to you is to plan for a short stay of at least one night and know that sometimes things happen and you might need a little more time to be ready to go home. Don't try to be a hero so you can say you went home right away; instead listen to your body after the surgery and let that be your guide.
