Hi ladies, when I first signed on with my CDC she told me anyone 5'7" and over can have four packs a day instead of three. But then I read on the CD website that only those 5'8" and over can have four packs a day. So I measured my height to make sure, only to discover that I'm just under 5'7"!!! I've been having four a day, so now what do I do? Continue? Cut back to three?
