Best of luck! WW has been a lifesaver for me. It can get a little challenging with the lower daily points. Remember to get your good guildlines in first.
I ended up switching to Core when I hit 22 daily points. It was killin' me having to count points for veggies, dairy and meat. Core gave me a little more flexability. So don't be afraid to give it a try if you find your daily points are too limiting.
