Many years ago I talked with a coffee broker about de-caf coffee and he told me never buy the junk on the shelf, they chemically extract the caffiene and it truly isn't caf-free. He said only buy the coffee that says water-extracted caffiene free, which is usually done by Tullys, Seattle's Best or any other coffee ony business.
Just sharing this b/c God knows we don't need more chemicals in our bodies.
