I was able to wean myself off coffee gradually adding Teeccino and simultaneously reducing my coffee quantity. It was so easy and the flavors Teeccino has are delicious! I ended up with zero caffeine headaches by doing this gradually. And whats even better, recently I had a cup of coffee for the heck of it, and I didn't like it anymore! It was way too acidic, and I've found I prefer the Teeccino taste which has a better, fuller flavor. Thank you Teeccino.
