Wow, that's the opposite complaint from what I usually hear
Sorry to laugh, but that seems to be the first place that most of us lose.
You still have a ways to go before you reach goal. My advice is to just keep on keeping on and see where it gets you. I lost several cup sizes which is common, but I know a few women who lost a lot of weight and still were large breasted. Unfortunately, we don't get to pick where the weight comes off first.
