I also follow WW but I do better with the previous plan than the new Points Plus.
The first few weeks are pretty hard trying to figure it all out but once you get used to it you will know what foods satify you and how to distribute them through out the day so it works for you.
You can have a huge almost point free salad for lunch and get right back on track
I do best when I plan meals a few days in advance so I know how to plan my days, I have less of a chance of getting off plan.
The most important is to write down everything and track it.
My biggest hurdle was all the tastes here and there that I was doing, once I got over that things fell into place.
I save alot of my trackers so I can go back and reuse the meals as I plan meals and food shop.
Good Luck, it works but it also takes alot of work to stay on plan.
