I'm on Day 5 and have peeked too, I wish I wouldn't have though, it almost discouraged me also. Mine said 2 lbs...which is not bad, but I think I just feel that I've changed things so drastically that it should be more, kwim? I'm really going to try to make it the whole 3 weeks and see what comes of it. I'm also interested to see if others post that the weight just all the sudden seemed to come off a bit easier.
Best wishes to you and hang in there.
