My doctor once told me that we sometime**** plateaus going down in weight as we did going up. Say your when you were gaining weight you sat at 215 pounds for a long time. Maybe years. Then all of a sudden you started to gain again for no apparent reason. He said your body gets comfortable at certain weight sometimes going up and down and can be one reason for plateaus. But, I hear you about being frustrated..esp when going down into the 100's. Congrats to you all!
