Hugs, JustB!! The week is behind you, you did pretty good considering! And that sick feeling you had? Remember it! That's what I try to do when I'm tempted to go off plan. Is a taste of something really worth feeling crappy for the night/day, whatever? Nope!!
It's one day at a time, girlfriend. And this time next year, you will be wearing those smaller clothes. Just keep your eye on the prize. That's all we can do. And of course, post here to 3FC so we can help you through it.
