Hi nedoglover,
I had my gallbladder removed Feb 8th. After my surgery I ate light for a few days. Broths or chicken noodle soup, jello, lots of water and juice. A couple of days later I moved up to soft foods, mashed potatoes, oatmeal, soup.
Now I'm eating a more normal diet, but staying away from high fat foods, milk products(except yogurt), and soda, because not only does it cause bloat, but also diarrhea.
You have to try different things and see what you can tolerate best.
