The man who introduced me to CS said about  15% of those who use CS for the 
first time internally experience a  stomach ache, which lasts about 10 minutes, 
as a result of the sudden  appearance of a positive charge in their stomach.  
The only time  I've felt irritation was when I took a couple tablespoons of my 
first  batch which was cloudy gray and very strong.
