I wonder if you start getting the greenies it means your getting closer to being cleaned out.Thats what i got 2 years ago but i went on some serious drinking binges and ate like crap for two years.This time i got the tan ones with green centers.They were also alot bigger and a hell of alot more of them.I hope to see some greenies on my next one.I think the greenies have spent less time in the gall bladder and havent built up a bile exterior yet.Do you guys agree?
