Input: I don’t know if the formula for this product has changed or my tastebuds 😳, but the strawberry flavor is so terrible! I purchased it a year or so ago and it was delicious, almost like a milkshake. This time I could barely get one sip down because it unbearably sweet. I got an instant stomachache...I would not recommend this product to anyone anymore

Do not purchase if you are sensitive to artificial sweeteners
