Nowadays, there are plenty of products gluten-free. Alternatives have grown a lot. I buy some delicious cookies from Jasmine, a French company. On Sunday, I do my own pizza with rice flour, tastes great! Staying without gluten has been easier than I had imagined. I can not say the same for dairy products, as I love cheese and yogurt (it is my French and German descent rsrsrs). But give it a try to stay a whole month without gluten and see the results on your body and how it reacts to it. Staying without gluten does not hurt our bodies.
If you are interested, there is a book I have read called Braved New medicine by Dr. Cythia Li, MD. Though it is not about epilepsy, this book has opened my eyes in many respects. It is about integrative medicine.
Take care!
