Nothing impressive did pop out except 'sesame seeds' in my stools... I had also been taking 2 or 3 capsules filled with cayenne pepper each day and I was looking for 'rice' - I've read around the forum and I know that 'sesame seeds' is a result.
On the other hand I did eat real sesame seeds on Tuesday (today's Saturday) so I'll try to get a magnifying glass to double check.
