I'm relatively strict about it, although I imagine some could have slipped through. But I eat mostly just fresh foods and stay away from processed foods so not much chance of cross-contamination. When I eat protein bars or protein shakes, I only use those clearly marked as Gluten Free and Soy Free.

I continue to eat my slow-cooking oats, though it doesn't say anything about gluten (doesn't say much of anything on it), because I buy it in huge bags.

Yes and no.My doctor said I can have a little bit here and there and that I would know when I've had too much. So, when I'm home and in control, I'm much more strict (but still allow for oatmeal and nuts that may have some). When we eat out (which is only a couple times a month), I try to research before I go to find the least glutenous items (meat with veggies, but no bread, etc).

I've been gluten free for almost 4 years now and when I do "cheat" (usually around the holidays, and only one meal) I can tell. My brain gets really, really foggy for a couple of days and I just don't feel right. So, I'm learning that even the cheats aren't worth it to me.
