I admit I was a sucker and bought these during a previous offering. Good gravy, these are awful! I could barely drink the concoction in to which this becomes mixed with water, the taste was blechhh!! The product might work as stated if one can get past the taste, but ugh!!! My bad, I bought four packs without having ever tried them (I'm an optimist, what can I say?), so that was a $45-ish lesson for me.
