I have a success story
When I graduated college (Jan 2005) my mother and I stated Weight Watchers. I started out 6' 0" tall and 345 pounds. I am not sure what my mother started out at. We encouraged each other through and after a year and a half I was down to 205 pounds. That is 140 pounds lost. I looked like a completely different person. My mother lost somewhere around 120 or so pounds as well.
Ok...now the unsuccessful part. I stopped going trying to do things on my own. I am back up to 261 and not happy with where I am now. At least I am back eating better now and I have found this site to be extremely helpful in controlling what I eat.
Just thought people would want to hear my (our) story.
