Hi, I'm finishing day six of the MC, I am keeping to the book. I am a little frustrated with my weight loss. I had lost 7 lbs as of this AM, when I got on the scale tonight I had gained back 5lbs! i know I need to wait until the morning to get an accurate reading but I still feel something is wrong. Is there any reason that I would be retaining (or gaining at this point). I have never done this before and I would appreciate any insight and encouragement. Thanks!
