Sometime ago I suspected that the caffeine in coffee and I didn't get along well. When I switched to decaf coffee I was surprised when I still wasn't feeling quite right. That's when I discovered that de caff coffee actually has more acid than regular coffee so I switched to Teeccino. Since I started drinking Teeccino without acid or caffeine I feel much better. I have replaced my coffee habit with Teeccino and I feel great! Thanks for the great tasting alternative to coffee!
