I'm one of those unlucky ones that got a stomach ache from taking Candex. I followed the instructions exactly, and with in 1 hour of taking my first dose, my stomach started to feel sick and wasn't able to eat dinner because my stomach felt so lousy. I also got bad cramps and went to the bathroom a few times times. I drank about two bottles of water to try and rinse it through my system, after a short nap and about 4 hours later I feel the effects seem to be mostly gone.. I hope.Now maybe they should have a warning on the bottle to start with a lesser dosage or something, I am afraid to touch the stuff now.It might be a good product, but some of us just are very sensitive or it doesn't work with out system.
