So I go to my favorite tea shop and share a pot of lovely Earl Grey with my friend. (I've only been gluten free for a couple months) Less than 10 minutes after finishing my tea I'm hit with TERRIBLE nausea. Two hours later it's vomiting and diarrhea. This lasted for EIGHT HOURS!!! I'm recovering a bit slowly and can't believe I used to feel like this every day before going gluten free. So- I'm guessing there is something in the Bergamot oil that flavors the tea that is not compatible to a gluten free lifestyle.
