I think (Dalia correct me if I'm wrong) that not all people get the healing crisees (how the heck DO you spell the plural of crisis - is it crisis?) and you only do if you've been eating alot of stuff that is silently poisoning your bod. So with me that was dairy, with Ruchie it was sugar. Even if the stuff you detox on is an IBS trigger for you, it doesn't mean that your body's going to have the reaction!
And then it's usually stuff like cold-symptoms or gas not really horrible symptoms like D!
