What I am trying to say is, it's a little early to " be glutened". If that is the case, you haven't been gluten-free for 2 days. You need time to get the hang of the diet, heal, get your intestines back in working order. That doesn't happen in 2 hours gluten-free or 2 weeks gluten-free or even 2 months gluten-free. In the beginning, anything can make you feel bad. You might just be feeling bad because everything is so messed up in there.
4 days. But I understand. I don't typically have much of an intestine problem when I eat purely gluten-free foods. I had no reaction with the Chex gluten-free cereal with our gluten-free soy milk last night (as an example.) Yes I could be having reactions to anything that I eat since my body is inflamed right now.
