We gave it one solid month. ...And we were stringent, dammit! For thirty days Max was absolutely completely gluten free. (Well... except for that one time Daddy made dinner, simple PB&Js. We both turned around at the stove bewildered as to why it all went off without a hitch, why everyone was so damn quiet and well-behaved. And there they were... ALL of them... stuffing their faces with bread. OOoops. It's hard to remember sometimes... but for serious, it was only that once.) On a gluten-free diet, Max tries to murder Lola, break windows, jump off furniture with wild abandon, scratch, hit and bounce his butt on nearly anything. ...Which is not really a big difference from any other time, sadly. Sometimes it seemed better and sometimes it just didn't. That's the pattern with Sensory Processing Disorder too. Sometimes it's okay for a spell and then sometimes... it just fucking sucks. I decided to take him off the gluten-free diet then and see if things got worse. Nope. The same. On a gluten-ous diet, Max still tries to murder Lola, break windows, jump off furniture with wild abandon, scratch, hit and bounce his butt on nearly anything. Without much difference in behavior, but huge differences in grocery budget and menu-planning, I decided gluten-free just wasn't for us. To note, his speech is getting better and continues to get better even when eating le evil white flour!
I knew it may not be the miracle I was hoping for. It was an "easy" thing to try though to see if it could potentially make life easier in other areas. I can see where it helped our family get healthier in other ways. Usually we had a bread-y substance at every meal before going gluten-free... post GF we still don't eat many biscuits, breads or rolls with our meals. It's still pick a meat, pick a vegetable, pick a fruit and go with it. Easy peasy.
I, fortunately/unfortunately noticed my face getting clearer from major rosacea breakouts I guess because there simply wasn't as much gluten-ous items to pick from in the house. I continue to stay away from gluten... unless there's cake. If cake is a choice, always choose cake.
So there it is for Maximus Prime. Would it work for you? Who knows. The point is, you just really don't know until you try... and compared to a lot of things, it is easy-ish to try. Give it a quick Google and you'll find out that some people SWEAR by a G-Free diet. I just want to remind you that, hey, everybody's different.
