I have done 4 flushes so far, the first 2 went very well, the last 2 were duds. My body and breath odor are still gone. Acne is still 80% reduced, with the last 20% flaring up every so often. I'll probably do another Liver Flush in the next month or two. After the last 2 duds I'm giving myself a break and focusing on diet and minerals.
Why are you postponing a liver flush? There's really no need to over-stress or over-plan it, and the results can really do some good. You could do it tomorrow and be done with it. Worst that could happen is you get a dud, and then you just do another one later on, changing some details. Just dive in! :)
