Gluten free hasn't been a magic cure for me, but I do feel a little better on it. Once you know what to look out for, it's not even that hard to cook for yourself. Eating out can be problematic, but that's true for Crohnies in general, I think.
Do you have a crockpot? If so, check out this blog: http://crockpot365.blogspot.com/ This woman decided to use her crockpot every day in 2008 and post the recipes, and since one of her daughters has Celiac, most everything is gluten free. Next time I go to the grocery store I'm picking up some extra milk and trying her crockpot yogurt recipe.
There are lots of books available that go into detail about gluten free eating. I picked up a few at the library, and the one I liked best was The Complete Idiot's Guide to Gluten-Free Eating. It had the most calm, realistic attitude about what ingredients to look out for. Some books come across as a little extreme and frightening. I got a copy of a cookbook called Gluten Free Quick and Easy for Christmas, and that seems to be another good one.
