ick!
I honestly don't know if it works - I tried one packet mixed with water & it was so nasty I didn't get more than 2 sips in.  Tastes less (not at all) like mango & more like shrimp shells. Spent the next 20 minutes trying to get the taste out of my mouth & I've been trying to figure out since what I could possibly mix it with that wouldn't make me toss my cookies.  Maybe the other flavors are better, but steer clear of this one.
