Anyone With A Kid With Totally Neurological Symptoms?

[Cinnamon]

Hello!

My 11-year-old was having terrible neurological symptoms and it took me quite a while to figure out that they were caused by gluten. When we first went gluten-free, he did great! Even he could see the dramatic changes. But now it's been a couple of months, and I think he's forgotten how bad it was. He is missing his pizza, macaroni and cheese, all the normal foods that most kids eat. He has to bring some food if he goes to a party, and has to turn down the yummy cupcakes and treats that other kids bring in when it's their birthday. His sister is also gluten-intolerant, but she is very good about staying on the diet because she gets stomach pains and ugly rashes if she eats gluten, so that's a good deterrent. But he doesn't have the pain and discomfort. How do you get a young boy who thinks he's indestructible to stay on a restrictive diet when he doesn't see the immediate effects of cheating? Any ideas?
