Fatty and greasy foods will usually make a gall bladder problem (including a lack of gall bladder problem) worse. Pizza, ice cream, fried chicken, french fries, fast food... those are all things to stay away from. If you can get your guts calmed down, you might find that you can tolerate small amounts of those things occasionally, or you might find some version that you can have. I have found that Red Baron frozen pizzas are okay, provdied I don't eat more than 1/2 of one at a time, and don't eat it more than once every week or two. I can also tolerte Chick-Fil-A because they deep fry in peanut oil, which seems to be toleable to me. Still, I don't press my luck and eat it too often.
My biggest trigger, though, is caffeine. I can tolerate it in chocolates and green tea, but that's it. Black tea has to be decaf and no coffee at all (because even decaf still has a good deal in it). I could drink decaf cokes, but the only kind I like is expensive and I've been off cokes so long now that I don't even really want that much anymore.
Have you seen posts on calcium? Linda (Inape) did a bunch of research on it and found that Caltrate 600 w/ vitamin D is the most constipating form of calcium on the market in the US, and that if people who have D take it, they will lessen thier D. Linda also doesn't have a gall bladder, and that's all she takes to control her D. I have more of a problem, though, and have to have my Welchol, but I take the calcium in addition to it as well, and that way I don't need so much Welchol. Calcium is also good when you have a bile problem because calcium soothes minor irritations in the digestive tract, which excess bile can certainly cause. They think it's the reason why people who consume 3 servings a dairy a day have a significantly lower occurence of colon cancer. Which makes sense, given that it keeps the intestines from being irritated. So it's helpful on that account as well.
