I actually went and "signed up" at a WW meeting just one time so I could get all the stuff -- the point slider thingy and the intro book. I also purchased the updated food and dining out guides, and the daily journal, but that stuff isn't necessary. Registration was free, so I didn't have to pay that, but I did have to pay the $11 meeting fee. Since then I've just been keeping track of my points and weighing myself on my own scale. I also write down all my points each day, as well as my weight each week (my self-selected "official" weigh-in is on Saturday). My mom and I are doing this together, so we're each-other's support. Plus I have you all and some girls at work for support. I considered joining WW online, but they don't have the points set up for nursing moms. I think it would've been a ripoff anyway. What I'm doing now is great for me.
Now I just need to get off my lazy arse and exercise...
