It depends what you really want to do?? If it hadn't been for this meal would you be thinking of going onto WS now ? If not, then you could ask yourself why you are changing your plans just for the sake of one meal ?? it's only a couple of hours to get through and you would probably feel proud of yourself for sticking to your plan afterwards. It's quite empowering going out and not eating, it proves to yourself that you are in control of food and it doesn't control you. Just cos there's a menu it doesn't mean you have to eat.Think about going back there next year, or before that, feeling really slim wearing a fab dress and not having any issues about your weight, rather than delaying the issue. Food will always be there !! Being with your son and your family in a nice place on a special day is what it's all about, enjoy that. Take a bar, have coffee and sparkling water or soda water. Take your camera and be the photographer taking pictures of everyone to keep you occupied. Just ask yourself how important it is to you to lose this weight and is this sort of event the thing that has got in the way of you losing it before. If so then don't make the same mistake again. It's just one meal !! you will be there with everyone and see your son enjoy it. It's a change of habit , which feels a bit awkward, not life threatening, and staying slim is all about change of habit and learning new ways of handling social and food situations. At least this is what I keep trying to tell myself. Good luck with whatever you do, RELAX about it, feel proud of sticking to your plan and enjoy having a gorgeous little three year old prince to cuddle.
