Well, the problem with laxatives is that (from what I've heard) they can be addictive and once you stop you would have problems going on your own. The lower bowel balance is made by the Barefoot Herbalist on who has a forum here on Curezone, and is non addictive and actually helps you uh...get parastalsis naturally. And it's gentle. It seems to me that The Master Cleanse is very rigid. You must do it exactly the way Stanley Bourroughs says, and I just don't like the swf and the accompanying "butt pee." The OJ fasting is easier, and MH says that he has seen people die from the power of the lemons, as they are very powerful. I have taken the lower bowel balance with the MC, and it was great as far as I was concerned, but then you get accused of not doing the Master-Cleanse properly.
Mind you--I am absolutely FOR the MC, any kind of fasting is fantastic, so don't think I'm trying to tell you to do something else. Just sharing experiences!
