That's a good question. But if you gain weight, there's no guarantee it will go to your boobs first. Have you taken any pictures to compare? I am uneven too and have grown on both sides, but my smaller one has yet to catch up to my bigger one. I use the breast enlargement without surgery video (www.breastenlargementvideo.com) since Jan 30th and have been massaging every night with bio-oil and 360 inward rotations and I've grown an inch, but its taken 3 months. I measure 38 inches around the bust, 30 inches underbust I have a brava that I use like the NB and just got the XL NB system and will start using that once i talk to my husband about it! I had some trouble with skin irritations and I know that he isn't going to like it if he thinks its damaging my skin, so I got some cocoa butter cream and I'm going to have a few practice sessions before I talk to him, just to make sure my skin does OK. I also just started adding in a few drops of greenbush enhancement blend liquid to my massage oil and got some Bustea too. I have't tried the tea yet.
