Webmaster, that was a great job that you did with the survey. I also admire what you did with the dye. I had a very unusual experience with liver flushes. The first two times I did it, I got no stones. After the third flush, in which I used Phosfood, and 12 ounces of oil, the following happened: no stones appeared during the next two days. On the third day some rock hard stones came out with a combined volume as big as two man's fists, about the size of a gallbladder. The biggest stone was 2 1/4 inches across, and was egg shaped. After that, I got no hard stones, but every night for the following five months I got one or 2 cups of soft stones and smelly multicolored sludge. I took photos and sent them in to you. The total volume of sludge produced by that third Liver Flush was about 5 gallons over five months. Very bizarre. The material had a very peculiar and strong odor, also. I found a few dead worms about the size of my little finger in diameter and five to 7 inches long. At the time I weighed 145 pounds and was 6 feet tall, and couldn't gain weight. Now, a year and a half later, I weigh 166 pounds and feel much better. I have a tough case of chronic fatigue syndrome. I still would love to find someone who could analyze this stuff or conduct a more rigorous experiment. I'm a medical doctor as well as a chemist, but at the present time, I don't have the stamina to visit medical schools to drum up interest in an experiment. Maybe I will soon. If there is anyone out there that knows of a lab capable of doing a thorough chemical analysis, I'd be willing to pay for some lab work. I did get on the phone and called all over the US to find a lab, but to no avail. I don't know any way that the body can create hard stones within hours or a few days. The problem with the dyes, is that the liver can chemically alter them. It doesn't always do this. For example, if you eat beets, the red color may or may not come out in the urine. I think that your survey was very carefully thought out, and a big step in the right direction. I have a suggestion. Put a feedback link on each question to allow users to type in improvements to the question. At the end of the survey, have a feedback link so that users can add questions of their own. That way we can all help you improve the survey. For example, there was no place in the survey that I could explain that my most productive flush yielded about 5 gallons of material. I know this is rare, but one other person wrote in with a similar experience. I did a flush just last night, and the first and only thing that's come out today is oil and bits of floating junk. I don't usually get the real stuff from the liver until about two days have passed. What we are trying to do is monumentally important, because there are half a million unnecessary cholecystectomies done every year in the United States. There are a lot of lives to be saved and a lot of sick people that need to get well, but with this negative stuff in the journals, medical doctors aren't going to pay attention. We desperately need data from a series of cases that we can publish. It doesn't have to be a double-blind study. It just has to be well thought out and logical. It would be much more convincing if we could get a series of say, at least 15 people.
