Great work!!
I know what you mean about not feeling a difference... I've lost 50 pounds and I don't feel like there's much of a difference, either. I know there is, but I'm so used to the smaller me that I'm not as excited about my progress as I was. What might help you is to find a picture of you at your high weight that really shows every lump and bump, and a picture of you where you are now (updating it as you go along) and put it somewhere where you'll see it quite a bit (or carry it with you in your purse or something). Reminding yourself of where you've been is a good way to realize how far you've come!!!
