You and me both. I have a salad everyday with olive oil\grapefruit dressing(organic of course!) that I make myself, or, use it as marinade for chicken and fish (the most tender chicken or tastiest salmon you will EVER have!) so I would say that you are doing a "maintenance clean" like me.
I've noticed that the past two Liver Flushes have not yielded many green pebbles like my first flush. SO!... with that in mind I would think that it might be from what I've been eating (mentioned above) on a daily basis.
