I've just had a BM. Well, I say BM, there wasn't any *ahem* brown stuff, the bowl was just full of parasites or flukes?? They were yellow & looked like torn up strands of cooked pasta. There were loads of them, I couldn't believe my eyes. Oh & they smelled awful, like strong urine (is that ammonia??). I also saw some small, red sticks. I don't eat little red sticks, honest ;-)
