No, there is absolutely no diarrhea or discomfort or weakness, so it does not interfere with a regular daily work schedule. Besides, it tastes quite nice if you include the skin of the organic uncoloured lemon and throw it all in the blender. I use 1/2 of a larger size lemon, 1 Tbs. of OO (Olive-Oil) and a cup of water.
I am no expert of understanding all the differences between all the different liver flush/ cleanse systems available, but I did not think it as powerful as a regular liver flush, don't think it would push out stones, but it does increase the bile flow and is considered a cleanse rather than a flush.
I would not see the mini flush as an alternative, but as something to complement the flushes with.
I did it as an introduction to flushing, and sometimes do it for 3-4 weeks in between flushes when I know I won't get around to doing a real flush
