If I were you, I wouldn't mess with Dual Action Cleanse. I've never done it, so I can't say much for the quality of the product, but I've heard lots of bad things about it. I linked above to a site called Infomercial Watch. Where there are numerous complaints against Dual Action Cleanse and the company manufacturing it. There are so many complaints, you can read them all day. Sounds like some sort of scam.
I've done the Colonix program. I actually just quit it last week. It was making me feel sick and I couldn't handle it. So, I am currently in the process of returning it. I made it to day 24 and starting throwing up, so I quit. I also had other side effects. I've been feeling better since I stopped taking the Colonix. I've heard good things about it, which is why I decided to do it. But my experience wasn't very positive. Based on my experience, I can't recommend the Colonix.
I am looking for a different colon cleansing product to use. Not sure which one. I'm not sure if I am going to do another colon cleanse or just do a liver/gallbladder flush. That's where I need to make a decision. keep us updated on which product you choose and how it works for you. Because I'm trying to decide which one to use myself.
