I'm sorta in the same situation, my problems is I haven't been constant with OCM so I can't tell for sure if it works or not for me.
However, the zits, could they be related to something else and not your wash routine? I know for example zits around your mouth mean hormonal changes, on the middle of chin stomach problems...I once read an article on that and but I only remember the places where I get them, and in my case is true. So maybe look inward rather than outward? Just my two cents ...and now you love me forever :)
