Yup, sounds perfectly normal. I lost 6.5 pounds my first week and then went down to about 3 pounds a week for a couple of weeks and then averaged out at about 1 to 2 pounds a week from then on. One month I only lost 3 pounds the entire month. It will fluctuate, but most people don't continue losing 4 to 6 pounds each week. 2 pounds is an awesome amount to lose in a week, I'm always happy when I'm down 2 pounds.
