I have not been diagnosed with celiacs, but definitely have gluten sensitivity. I cut out both gluten and dairy 10 days ago. I'm definitely having withdrawal issues. The first week was mainly exhaustion, aches and pains, minor irritiability. The last few days I've dropped into a serious depression - crying spells, inability to concentrate, terrible irritability and insomnia. Anyone else have this. I was just reading that gluten and casein affect opiod receptors so withdrawal can be nasty, but I didn't think it would be this bad!
