Hi RockerMommy. I lost 60 lbs. doing what you describe back in 2002. I did have experience from going to meetings, though, so I knew the program. I always tell people who have never done WW that they should go to a few meetings to get to know the program. However, I think people can still be successful following the program without the meetings.
(Got down to 196 that time, then 30 lbs found me again, now I've removed that plus 20 more!)
