I think the basic message in many posts above is to shift your focus from what you can't eat to what you can eat. You need to keep a corner of one eye on the can't eat list too, especially when eating out, but mostly you just need to build up a repertoir of foods you like and that work well for you. There are lots of options out there, and learning new recipes can be fun.

At least, that's what I keep telling myself, living on a low fiber diet in a high fiber world. Not exactly the same problem as yours, but shifting my focus away from "Darn! But I love raw fruit and veg!" to "Hmmm... what can I do with this?" has helped enormously in terms of my spirits. And my guts are doing better too.
