It is possible the stones were imbedded in the stools, but the reason for taking the magnesium citrate (or
Epsom Salts )the following morning is to push out the stones.
Try another flush and make sure to take the magnesium citrate the next morning. I always follow Dr. Clark's recipe, so I am not familiar with the coke flush. Be sure and post your results!
Good luck and good health!
