I was wondering how long the intervals were between each of your liver/gallbladder flushes? My husband and I have completed two in the last two years and the second was not as productive as the first. We are going to include the second olive oil/grapefruit part of the cleanse in the morning in hopes that we have a more productive cleanse, expecting to see the tan clumps or darker stones. Any help would be appreciated, especially regarding the time in between your very productive cleanses!
