I was just wondering if you were having trouble with constipation before your cleanse? Or is this something new?
You might want to try doing an enema or a colonic to help clean out what might have been left from the cleanse. Did you really get out about 100 marble size stones? Marbles are pretty big. I usually get out pea size or smaller. If you had marbles, you might still have something stuck and that could be what is causing the discomfort.
You could also eat watermelon. That should get things moving. Plus it is good for your kidneys.
