Check out the different recipes on the Liver Cleanse page. There's one that only requires you to drink a couple of tablespoons each of OO (Olive-Oil) and lemon juice at bedtime + apples and/or apple juice (unsweetened is best) throughout the day along with a relatively "clean" diet. Do this over time and you'll pass stones. Don't risk the grief of trying to do a somewhat more radical flush if you haven't really prepared...it's not worth it, generally speaking.
