I have recently ordered the THRIVE Plus - Café (1 box). I drink coffee every day and have no problems. When I drank this first serving of the Café I had painful diarrhea and a horrible stomach ache that lasted all night. (I did not drink the coffee on an empty stomach) I could not drink the rest of the packets and have requested a return. I have never had such a reaction to anything like this before. For $37.40, (14 individual packets) it gave me a horrible and painful experience!
