Several years ago I was diagnosed with Interstitial Cystitis (aka - painful bladder syndrome) and could no longer tolerate anything acidic,including coffee. I tried various coffee substitutes and they all came up short. So I turned to herbal teas and this was a hit or miss result, some teas would bother my bladder others wouldn't. Besides, they weren't satisfying like a good cup of coffee. Finally, I was fortunate enough to come across Teeccino coffees in my local health food store. At last, a great tasting cup of 'coffee' with no side effects. I am once again happy.
