This was the worst thing I've ever had... I'm surprised at how many positive reviews there are. I tried the watermelon this morning, so maybe other flavors are better, but I can tell you right now that this was awful. At first sip, it felt grainy and nasty, but still tasted alright - but that was until the aftertaste hit. I haven't been able to get the taste of this stuff out of my mouth all day. It's making me physically ill. Would not recommend to anyone.
