<<Disclaimer: Verify this information before applying it to your situation.>> Well, this is gross. But I just started eating Dairy again with Lactaid. I haven't had any gut problems, until today (which is about 1 week since trying it for the first time) when I have had really painful bowel movements including burning while passing the stool. It seems Hemroid-like, though I'm not sure. Does this seem like a dairy thing or a gluten thing? It's hard for me to tell. I'm sorry it's such a gross topic, but I know Celiacs are used to talking about gross topics! Oh by the way, I checked the dairy products with the mfr's and they are GF. JP
