dh gave ds2 a bottle of expressed milk right before I was out of recovery, so he did not want to eat. DH had no idea when I would be out of recovery so he was just doing the best he could. It was actually later that evening before ds2 was interested in nursing. Once I was home, I think I did fine with over the counter pain medications and did not need super strong meds.
I would find out as much as the surgeons can tell you about your particular gallstones. While I was fortunate enough to have outpatient surgery, my SIL had gallbladder surgery and due to the adhesions from her frequent gallbladder attacks had a much rougher recovery.
