Ginny,
Hey there! Keep your chin up! I think 6lbs in two weeks is excellent! Keep in mind that the more you weigh, the faster you will drop weight. For some its slower than others. Just keep in mind that its not just what the scale says but what your body and your waist line say. Give it time, you are still healing. Just wait, I bet in two months, you will be down at least 40lbs. DON'T GIVE UP!!
