[BreastsPlease]

Thank you all for the advice! I think I have decided on my routine (subject to change if it seems to need modification):

-- 6 g L-Arginine
-- 4 g L-Ornithine
--Birth control (I found out that it contains estrogen and progestin, so I think that should help.)
--Exercise (5+ days/week):
~3x10 wide-armed push-ups
~3x30 sec: place palms together, elbows straight out so that forearms are in a straight line, push palms together as hard as you can for 30 sec, repeat 2 more times
~3x30 sec backbends
~3x30 sec handstands against wall
--Sleep on my back as much as possible (See this article: http://www.bustle.com/articles/11321-6-surprising-things-you-didnt-know-about-your-breasts) Sleeping on your back is the best position for keeping 'em perky. I also found it interesting that about 65% of women have a larger left breast than right, because this applies to me.
--Massage 15 minutes, each in the morning and before bed, with Mederma stretch mark cream (I've gotten stretch marks on my breasts before. Thank goodness they've faded for the most part, but I want to prevent it before it even happens this time.)

That's it! I'll do my best to keep up with this routine, and post pictures again in a month!
