I've taken a similar flora product for about four months from  
lifeforceplan.com at the beginning of the year while on the candida  cleanse 
and used a 
stevia powder made with it and experienced no side effects.  No unpleasant ones 
like that anyway. As I understand it, a lot of beneficial  bacteria [I assume 
that's what your flora product was] products use  inulin because the ''good'' 
bacteria are so well nourished by it.
