Yes I've just found that out but I did do 2 enema's one after the 7am epson and one after the 9am. After that the flood gates opened. Not sure if what came out was stones. Small brown and round about the size of a lentil. I counted 57 after my 4th visit to the bathroom. Any other info would be appreciated. I'd like to think it was successful but I'm still unsure.
