nausea/vomiting
"I am 11 days post op from emergency gallbladder surgery.  Been having severe nausea again just like I did before my gallbladder surgery. Having trouble with eating. Went today and had my post op visit with the surgeon. Told him I've been feeling really bad and nauseated. Lost 10 lbs in 11 days. He prescribed zofran 4mg every 8 hours. Insurance paid for 30 tablets. I also have a refill. Started today. I took my first dose about an hour ago. I actually feel good. The nausea has subsided. So far no side effects."
