I have been using this product for 3+ years when Costco use to sell it. Then Costco change to the organic which I did not like and found it on amazon. I was very excited. The product and the cost was the same as Costco. I have this on auto- delivery every month and received the new flavor. At first I thought I did something wrong. It was thicker than usually and I had to add more water to thin it down with the yogurt and berry mix I make. Then the taste. It's a lot sweeter than before and I really cannot describe the taste. It leaves an after taste in your mouth. I had to check other reviews to see if anyone else experienced the same and sure enough. I am not the only one. I do not understand why the manufacture had to change anything about this product. It was fine the way it was before. I cannot eat this. I have a full bottle that I don't think I can make myself finis ith. I am canceling my auto-delivery. Bring back the old formula, please!! You will lose more customers specifically those who knew what it use to taste like before the change.
