Query: Worst Protien Shake

I bought the vanilla creme flavor. It tastes very bad. I bought a four pack about 6 months ago and I hve tried to drink three so far and been unable to finish any of them because of the artificial sweetness being overwhelming. I was suprised that this would be so bad having many other brands of RTD shakes that are excellent.
