Good luck to all of you. I am 3 weeks post op from gastric bypass. It has been hard. I know I am getting stronger everyday. I was in the hospital five days. I was having issues with nausea and vomiting that was likely anesthesia and pain medicine related. My advice would be to speak up and ask for what you need. You are not bothering the nurses. It is their job to take care of you. If you are having issues then they will get you approved to stay longer through insurance.
