I agree generally with what Sam has said apart from one thing, after 2 months on the herbs I would think you are probably about a month or 6 weeks short of when you can expect to feel the growing pains start. 3-4 months in, seems to be fairly typical.
I believe that the older you are the less that areola growth can be expected, although enlarged and darkened actual nipples should happen relatively early. I would say that my areola growth is minimal if any, although they are darker after 8 months from when I first started and just over 5 months since my first growing pains.
I started on a similar regime to you but switched to SP plus PM after 6 weeks and haven't regretted that change - not saying you should do that, its entirely a matter of choice, but my avatar piccy was taken last weekend.
Hope that helps, the only other two ingredients you really need to add to your list, are I'm afraid, "patience" and "perseverance".
