I also started at a size 30 a year ago. When I had my psych eval, the psychologist asked me what I though the lowest size I could get to would be, and I said a 12, but my secret wish was to be a single digit. She said she saw no reason I couldn't be a 4 or a 6 (i'm only 5'3). I almost told her to put down the crack-pipe.
Yeah, she wasn't smoking, apparently. I'm there. Being a 4 on top and an 8 on the bottom, now, is almost surreal. Just wait, you'll see. It's entirely possible.
