Just wanted to share my surprise and good news.
I just went shopping since my pants were getting ridiculously baggy. I was happy to discover that I had gone down from a low size 18 to a perfect fit 12, and in 3 different stores mind you (Gap, Banana Republic and Loft).
Its weird because I used to be a size 6 at 128, but now I am a 12 at 154. I had been getting discouraged by the scale, but it goes to show that the number on the scale isn't entirely everything (I had done my measurements last week and noticed I had lost several inches as well, but didn't think it would make such a difference in clothing size!). At least I now have a decent outfit to wear for Christmas.
Best holiday wishes to you all!
