I just read through this entire thread, lol. Kudos on you for starting up Weight Watchers! I plan to join WW after LO is born, because it always seemed like the most reasonable, healthy plan to me. I mean, you can eat anything you want, really... just in moderation.
Over 3 lbs down in one week, that's awesome! Keep it up, you're doing great and you'll be down to your ideal weight before you know it!
