I love Weight Watchers online.
It does give me more points than I need, so I take a few off (I think it gives me 26 points and I'm using 23 points, it used to give me 28 points and I've used 23 points since having DS).
I love the food tracker and how easy it is to use.
I got 4 months for $65 so not too bad. I'm hoping to have my baby weight gone by then.
