Go cautiously if you are gonna do these flushes or fastings...while on NB...your body may become more tired while doing NB for a few months while you are detoxing with the recommended stuff from NB. Just my opinion on this, plus I've read other do Liver Flushes and felt much worse. The main goal is to keep your bowels moving daily to rid the body of the toxins you are eliminating.
Just a head up...sometimes more is not better...hope you don't mind me butting in..just concerned :)
