I have suffered for years with acid reflux and migraines so I stopped coffee a year ago and was given this wonderful coffee substitute from one of my students. I was thrilled when I read that it was good for the digestive system! No more migraines or acid reflux and I didn't have to give up that great coffee flavor. So many choices too. I give this product 5 stars! I have recommended this non-coffee to several teachers and friends. They are hooked on Teeccino and unhooked from caffeine. Thank you so much for this delicious alternative to coffee.
