Nobody has a perfect diet. If they did they wouldn't be reading the Liver Flush Forum on curezone.com :)Like I said, I didn't fast at all, except for not eating after about 1:00 the day of the cleanse.
I'm no pro, but I'm guessing that assuming you did the cleanse correctly, either you have way too many stones to pass large, noticeable ones. Or because of your bird diet, have no stones. Dr Clark says everyone has stones, and I tend to agree with her, so I'd say you just got bad results the first time.
During your first cleanse, did you follow all the instructions? Did the Epsom Salts work correctly? Are you sure you didn't get any stones out? I didn't strain mine, but definitely saw a whole lot of them floating on the surface. Next time I'm gonna use a strainer, even though it's kinda nasty.
I'd say go for it again, you might have better results!
