Many longtime loyal consumers of Sierra Mist (in all its varieties) are dissatisfied with the new formula that includes purified stevia leaf extract and potassium sorbate. The taste is bad and the after-taste is worse. Not to mention the physical ailments suffered by many who unwittingly consumed the new formula as there were no public announcements or advertisements regarding the changed formula to include purified stevia leaf extract and many of us bought the product thinking it was what we always trusted it to be. I personally will not purchase their new formula or any of their products as alternatives. I want the original Sierra Mist back.
