I completely understand! There have been several times when I went to WI feeling "light" and just knowing that I had lost big - only to see the scale stayed exactly the same! It's a little depressing, but I have to remind myself that I've lost 25 pounds that I wouldn't have lost otherwise! In fact, I'm notorious for gaining over the summer - I'm a teacher - so I know I would have gained if I hadn't joined LAWL the day after school let out!
Have a spectacular day!
