Just curious-why are flushes so different??

It seems that even with the same person, each flush is so different. My first flush, just after the master cleanse, was very successful. I've been told that it was probably gb stones as well as parasites (many parasites!) My 2nd flush on the 21st, was successful, but almost all green stones - a few large ones. Unfortunately, since then I've gone back to eating really poorly and want to do the cleansing fast again-will start this week.
Also, as long as I'm here, I've tried asking in pet forum and parasite forum with no responses (!) - does anyone know of the co-q10 formula for pets??? How much and how often? will they get the runs? Will I be picking up visible parasites in the house?????? Please advise! Tweet
