"I got a free sample of the Vanilla Caramel. It SMELLED good, and when I mixed it up and took a sip it was OK. I went back to my cup a few minutes later and it was all thick and gritty, not good at all. This produce isn't good for post-ops because we have to drink over a small period of time and apparently the drink gets gritty if it sits too long. Didn't care for it."
