Yes I have too I read on here that people suffered from constipation, but not me..... It was in the first 2 weeks but did settle down after a few days.
Since week 4 I have had the old rabbit droppings, and I did try fiboclear which my chemist gave to me free of charge, however that just sent me running to the toilet so will just try and leave nature to take it's course in future lol x
