My sister is gluten-intolerant, so I’ve been in the habit of looking for GF things. I should probably cut it out too…
Don’t even lick envelopes any more. Check cosmetics, shampoos, etc. for wheat products.
Watch for cross-contamination in the kitchen–wooden utensils, sponges, the toaster, etc.
On the up side, look at different cuisines that aren’t based on wheat and focus on what you *can *eat. (lots of Asian cuisines, for example)
