I do the meetings right now but I sometimes think about switching. I love my leader and meeting in general but it's 30 mins drive each way and not as early in the morning as I'd like. I've tried a few other leaders/meeting times, but just haven't found a group/leader that comes close to comparing. So for now I'm still going, in the future... who knows.
There's a lot of support to be found here. And if you need more accountability, there are challenges in different forums. (There's also a forum called Chicks up for a Challenge.) There's a thread here where you can post what you eat in a day, if you think sharing that will keep you honest.
If you know someone that is trying to lose weight too or might be interested in that, having someone to talk to about that might help too. My best friend moved to Sweden some years back and she's struggled with her weight as well. We can't work out together and she doesn't follow WW, but we can ask each other about our workouts, tracking, etc. She posts on 3fc now too. We both joined a challenge on the same team. Some days when I really feel like slacking, she helps kick me into gear via IM.
