Hi Cici, I would like to do the liver cleanse, but I'm afraid it'll be to rough. Is this a very grueling procedure? I don't want to throw up as well, does that happen? How bad is it, REALLY? Now, do the circles under the eyes come from a clogged up liver, or from something else? Are there other things that bring that on? Also, does it matter what time of day you do the liver cleanse? You see, my schedule is not "normal", I sleep during the day, and am up at night, so does it matter? thanks! stars
