I'm not breastfeeding, and haven't for months. I guess you could technically say that I have lost a great deal of weight in 3.5 months, but 7 lbs of it was baby, and many pounds were amniotic fluid, extra water retention, and other lovely pregnancy stuff that I carried around for the baby. I got down to 150 lbs fairly quickly, but then stalled out there for about 8 weeks. I'm finally starting to lose again, it's just quite slow compared to the last time that I did this diet.
