I've been reading through this forum and find it very interesting. I'm considering trying a flush (when I have a free weekend to spend in the bathroom!) I'm interested in doing this as a preventative measure. I don't *think* I have any stones (never had any problems). My problem is, I am really nervous. I'm expecting diarreah, but wondering if that includes extreme stomach pain/cramping? Also, I know everyone is different, but if I were to start this on a Friday night, would I be okay by Monday? (I really don't want to go to work with diarreah and cramps!) :-)
