I was feeling like that a few days ago... almost like I had not lost one dang pound... chalked it up to my body adapting to the weight loss, like it was adjusting to the new size. I was even on a mini-plateau, which has left, thank goodness. I only dropped 1/2 a pound, so I know that it was not a big loss of weight or even water that made me feel light again.... but it sure felt like it...
