Gravity, I eat sauerkraut several times a week and drink kombucha tea often. Also have natto and sugar free yogurt and goats milk kefir, so I may be set for fermented foods?

Chicory does not contain any caffeine, so I doubt it’s playing a role here. It’s used as a flavor enhancer and to save money on bulk coffee usage. How do I know this? I had a French grandmother.
