Your weight will fluctuate from day to day and even hour to hour, which is why experts recommend we not weigh ourselves more than once a week. The bulk of that 6 pounds is probably due to water retention; a big binge usually includes lots of sodium, so you'll retain more water. Not to worry: you know you fell off the wagon, and now you just need to focus on making better choices the rest of the week. Drink lots of water, eat your freggies, and get your exercise. It may take some time, but the weight WILL come off! The scale is only one measure of your progress though -- more important is how your clothes fit and how you feel. Hang in there!
