I bought this flavor for my wife. Tried it myself, I like it but I'm not a huge sour-ish flavor fan. My wife on the other hand fell in love! She loves the flavor so much. She was sad that she ran out so I'm buying her another tub. She loves the flavor, and she says it hasn't bothered her stomach at all (which is an issue with a lot of other drinks for her), and it helps a lot with her energy throughout the day.
