Why does it have to be coke?

I don't want to put the chemicals from the bottle of coke in my system. I've just spent the last 6 weeks eating very cleanly, and am finishing a colon cleanse, and then will start my parasite cleanse. I plan to do a liver flush at two week intervals, but can't I use something besides coke? Like grapefuit juice or something?

I just found this forum today. I have spent the last several hours reading most of the forum topics, and I completely agree with everything Doc Sutter says, but I don't see anywhere that explains what it is about the coke that makes it productive.
