Yes, I know how you feel. No one was noticing anything different about me, even though I don't see my colleagues regularly, so I figured someone should have seen something different! Then, someone noticed while I was at a conference, and it was such a rush! I think it feels better because we can't really see a difference since the weighloss seems fairly painless, but intellectually, we know there must be a difference (our clothes are baggy, the scales read lighter) and it is reassuring to know that we look better now to others.

Way to go.
