Congratulations!!! I am in the same boat as you, I have hit a HUGE plateau (try 6 mos!) after losing almost 70 lbs!!! Yea, like someone else posted, the first 5 lbs or so is water, but the rest is all you, er, not anymore, anyway!!!
When I lose, it's always the chest area!!! I went from a 42C to a 36B!
