I HAD A SIMILAR EXPERIENCE so i quit using hula clark for now until i can get the stones unstuck. so i started doing a kidney tinture, liver tinuture and i made my own hula clark formula for Clarkia ( Black-Walnut hull, worm wood and cloves in tintues form. for a week before my next cleanse. then i did the classic elcelanse for the next 2 cleanses. i then did The Master Cleanse diet for 4 days that night i did the claude lewis cleanse. it did make me sick and weak. i took 12 tablespoons of tomasto sppon to soothe my stomache. but well work it. i now am doing 1/4 cup olive oil and 2 tablespoons of lemon juice every night before bed. i passing a few stones( about 20?) every night from 6 - 8 p.m. this is what worked for me. i am not an doctor just my experience.
