The first thing to do when you get home after your diagnosis is to clear your house of anything with gluten. Some might say to indulge in all your favorite gluten things one last time before the big farewell. If you think this would work for you, go for it. It will probably leave you feeling dreadful, and most likely gorging today won't take the edge off missing these items tomorrow.
Getting gluten out of sight and out of mind is your best bet if you want to make your home a safe, gluten-free environment. You may come up against resistance, especially if you have a spouse and kids who don't want to give up all their favorite things along with you (although, chances are some of them suffer from gluten intolerance themselves, given the hereditary linkages prevalent with this disease). To coax everyone on board, assure them it will only be while you get your bearings. You can tell them that once you understand how to eat gluten-free, it won't have to be such a strict environment. You will, however, have to try to avoid cross-contamination as best you can by using different utensils, cutting boards, etc.
