It can't hurt to try reducing portion sizes? Obviously if you're hungry you need to eat, and you're really good at superfree snacking anyway. I don't know what to suggest!
When I did SW years ago I stuck to plan religiously but was only losing 0.5lbs a week or STS. I always had more than 1/3 superfree but I was having pasta/rice/potatoes/noodles with every meal. This time I've tried to keep it down to once a day and my losses have been much better. I try to be plan-neutral until my evening meal and that seems to have helped. It might not suit you (your menus sound so much lovelier and more varied than mine!) but it might just give you a kickstart week if following the 7-Day Plan doesn't do the business.
