Colon Cleansing: Have They Been Effective For You?

Still on the subject of losing weight. A friend had suggested colon cleansing for weight loss. I'm sure you've heard about it too.

My question: what's a safe brand to use? I've scoured the internet for raves and reviews and I just can't seem to decide which one to choose from the gazillions of colon cleanse products out in the market.

If you've done colon cleansing before for weight loss purposes, I would love to hear your personal feedback about it. Please, no business advertisement. I want to hear it from a real person who has personal experience with the product and how it was effective for them. Thanks! :)
