Remember the last time you laughed out loud in a movie or with your friends? Perhaps you even had belly laughter—when you laugh so hard your belly hurts? Remember how good you felt after that? It's because your opiate receptors were stimulated and you now have a little more endorphins circulating in your bloodstream. Well, gluten and dairy can mildly stimulate these same receptors. And just as an addict may have withdrawal symptoms when they stop their drug of choice, such may be the case with gluten and dairy withdrawal. My friend William Davis, MD, author of Wheat Belly, even came up with a name for it: wheat withdrawal. The same may be true for removing dairy or sugar.

If this happens to you, don't be surprised. First of all, this may be the first time you had to give up some of your favorite comfort foods cold turkey. And these favorite foods become comfort foods for a reason: Sugar-laden foods, especially refined carbohydrates, are highly addictive. Your body is actually going through a gliadin-casein-sugar-derived opiate withdrawal.
I've found that a small percentage of people might feel tired, depressed, or even nauseated for about two to five days after they stop eating wheat, dairy, and sugar. They can't exercise and often have headaches. It's the same mechanism as the two- to three-day withdrawals that so many folks experience when they give up coffee.
Dr. Davis believes that wheat withdrawal can be quite unpleasant for close to 40 percent of the population. That has not been my clinical experience. Our number has been closer to 10 percent, which is still a substantial number. You may have a friend or family member who has tried to go gluten-free and has told you, "My body must need wheat. It's been 3 days since I've had anything made of wheat, and I feel awful!" This response can be scary. But remember, it's not that the body needs wheat; it craves it. This is just the body craving a toxic substance that it has gotten accustomed to.
Don't worry: The symptoms will disappear quickly. And best of all, the cravings for sugar and wheat will subside, and then you feel wonderful! To lessen withdrawal symptoms:
