I sooo hear you, McFatty!
I also was wearing a 44 DD, but feel much more comfortable now in a 40D. I also notice how more comfortable I feel. I went into a running store a month ago, and bought a great sportsbra. I wear it all the time, even when I'm not running. It makes me look smaller, but it is so comfortable and supportive. I can't wait to lose even more on the breasts. I find though that because I am losing weight there, I am sagging more.
I hate, hate trying on bras, but I look forward to trying on bras now. I really hope to someday buy something in a la senza or lingerie shop. I know they carry bigger bras now, but not always as high as the size I wear right now.
