No stones, but I'm not cleaned out...

I have been doing Liver Flushes off and on for 17 years, with some big gaps in between when I just got lazy... So, it has been a while since I have totally cleaned myself out. My immune system has been really low, I have been having hives, and have seen many of the familiar signs that I am in need of "deep cleaning"... In the last couple of months I have done three cleanses, and the last two produced no stones... I really don't believe I am clean, as I am still having symptoms and the first cleanse produced a lot of stones, some fairly large. Thoughts? Please and thank you:)
