Hi 10 days post op and they do give you pain medicine at the hospital I was at but in between getting the pain meds I would get super nauseous too especially since you don’t eat anything . The incision pain made it hard to walk as well. I think everyone is different but my first week was brutal. The pain meds I got sent home with upset my stomach so bad I was up all night with stomach pains. I hope it’s way easier for you , some go through it all just great and hardly pain.
