no results to liver flush! why?

Hi last night I did my 3rd flush. It's been about one month since my last flush, which produced about 100 stones. The 1st flush produced lots of sesame seed size stones. This 3rd flush produced none. Why? I followed Dr. Clarks version again. I fasted all day though, and I did my epson salts. The only thing different I can think of is when I squeezed my 2 grapefruits, I also ended up eating the whole fruits too. I was hungry, and the grapefruits were so fresh, I could not resist. After I drank the mixture I went to bed. I've been pooping all day today, but no stones. I guess I'm a little disapointed, but I wont give up, I will do a flush again next week. Is it too soon? Let me know? HAPPY NEW YEAR TO ALL OF YOU! Barbi Tweet
