Thanks Crest! lol I called them and they were like "Oh, well that's not supposed to happen" Well duh. I am getting refunded so that's good, but still. You know that sensation where you eat too many Sour Path Kids and your tongue hurts? That is what my tongue is like 24/7. No bueno.
I am sorry about your celiac, but is it really Crest's fault that you are allergic to something in their product?
If it's an allergic reaction due to Celiac, then I think it's important they know so they can track that and see if a warning on the label is necessary.
