Happened to me to, first in the beginning when I did not know how to get results, then my 4th was not much, but my 5th and 6th were spectacular. Could be not many left, Moritz said two consecutive flushes of twenty or less and your considered stone free. Don't attribute your results to the castor oil pack, every flush is a little different. Many will give different flush times but I also think Moritz said three weeks max, but every month is preferable. The last thing I read said every 7-10 days!, I'm thinking on going at three weeks, I'm kind of impatient.
