Actually you could be in the hospital up to 3 days after an RNY Lapriscopic procedure. I had my surgery on 6/10/04 and came home on 6/12/04. I have had a c-section and hernia surgeries and both of those surgerys were much more painful than the RNY. I only used Tylenol when I returned home.
Listen to your doctor's instructions about what to eat when you get home and listen to your body when it tells you are full. Don't over do it.
I wish you the best!
