This happened to me on about day 5. It's like everything that is stuck up there for years comes out! (Sorry - TMI!)
Keep on - you are doing great!
I lost another 5# over the weekend :O and I'm about 2/3 to my original goal. Yay!
Can't say I'm really hungry. I did go out with friends this weekend and Saturday night at a cafe I ordered iced tea while they ate their salads and I did fine.
