I was doing pretty well and then went on vacation with a friend who loves to eat, and not necessarily all that healthily. I did regain a pound but I look at it this way--if I hadn't been doing WW, I would have ended up even heavier, I made the better choice wherever I could (sushi restaurant rather than Italian, just one glass of wine in the evening) and enjoyed them, and to be honest, I realized how much healthier I am eating on an everyday basis than I used to.
