Thank you so much @pegleg84! I haven't had dairy in a month now, and no improvement (other than not having another sinus infection) so it's gotta be something else. Eggs are casein-free, right? Maybe I should try no eggs, soy and/or corn. I really haven't been having those frequently though..
Has anyone ever considered their intolerances to be connected to Leaky Gut syndrome? Or tried the diet and noticed any difference?
