you meant the SCD Yogurt when you said "SCD" in your post, I didn't get that at first, I thought you meant the SCD Diet in general.
so I am assuming you mean that I will need to be on the yogurt for a couple of weeks before I notice gut changes. If I do that and I still get whiteheads would that imply to you that I am not quite ready for it or perhaps something else?
I will dowse for that for myself and see if it is a fit.
