Wow, so many in the one-month club (me, too!). I noticed my nipples after about a week or two, they were standing at attention, even the areolae, and I was a LOT more sensitive all over! Now at about a month, hardness is a thing of the past, more or less, but I enjoy myself a lot more, if that makes any sense. I measured my chest this morning, and I'm technically a 40AA. I "think" a month ago I would have been slightly smaller than a AA cup. The shape of my breasts has changed a bit, they seem a bit fuller. I cry a lot more easily. But I feel more serene, more alert, and more wonderful.
