WOWWWWWWWWWWWWWWWWWWWWWW - that is great news. 100 pounds lost is a real special achievement - I hope you are celebrating this amazing loss. You wanted it and you made it happen.
I think it's important as you get closer to re-evaluate your final goal - I don't think we know what it will be until we get close to the reality. You must feel soooooooo very good.
