You may keep passing stones for a couple of days, considering that you did not take any Epsom Salts .
Epsom Salts help a lot to have a nice flush. They relax and stretch ducts, block absorbtion of toxines that your liver release during flush into your intestines. That can cause nausea, fatigue and general discomfort. Epsoms cause diarrhea that help you to get rid of all those nasty toxic stones on the first day after flushing.
So the best thing you can do now is an enema. You need to wash flush product from intestines to start feeling better.
