laura, from what I have heard from people that have started the new plan last week (other helpers that had been given the plan one week before me), the new plan actually works better than the old one. One of my friends on the Weight Watchers official board is a helper in another meeting and got the new plan on Thursday 2 weeks ago. last week she lost 3 lbs and this week she lost 2 lbs. She had plateaued on the old plan for a very long time, losing 1 lb and putting it back on.
As for me, I have started the new plan on Monday (I mean, I have calculated what I have had on Sunday too after receiving the new plan, so I have actually started using it from Sunday). On Sunday I went out as usual to the Chinese and I have converted what I had into propoints the best I could, noticing I have used probably 28 propoints of my 49 weekly allowance. Monday Tuesday and today I have used only my daily points allowance, but I HAVE indeed used it all and I haven't cut on anything, I also had a lot of fruit which I normally never had. I feel nice and full every day. I step on the scales every day also (which I know is not advised by WW but I like it, my personal choice) and the scales have had the EXACT same reaction that they usually have on a normal week on the other plan. on Monday I was 3 lbs heavier than Sunday (because of the Chinese meal), on Tuesday I had lost 1.5 lbs of that and this morning I was back to the weight of Sunday, like it usually happens. BUT while normally I'm hungry in the end of the day and just fill myself with water, now I feel nice and full!
I'm sure you'll be able to lose the weight for your wedding. And by the way: you get married 1 week before me!
