About the acne, I have problems with it (at 37), and it always gets worse on the cleanse. But it's always better after. Cleanse your affected skin very gently but often on the cleanse. Perhaps try taking hot/cold showers to squeeze extra toxins from your pores, being sure to wash at the end so the last toxins aren't reabsorbed. I have also found Epsom Salt baths to help. My skin feels cleaner and softer, and it helps my achiness at the same time. I don't measure, just pour some in and enjoy a 20 minute soak.
Hope this is helpful; I'm certainly wishing you well on your cleanse!
