Query: Yuck!

I have the powder form of this colon cleanse, and yuck, it is terrible! It does not disolve in any liquid, even hot water. I tried masking it with Odwalla Superfood juice, but even that cannot hide the terrible dry taste of the powder. It's like eating dry fish food mixed with sand.On the other hand, it gets the job done...if you enjoy pooping a lot...
