I will chime in too, both about sharing the frustration AND the uncertainty about what will work. One thing I do believe in is that the progress is there, however sometimes at a pace so slow it cannot easily be observed. Nanci, you have gone a very long time with no loss, but you also have the knowledge that you maintained a 50 pound drop over 7+ months, without hunger or "suffering" (or so I hope).
I wish we knew more about why the WOE slows to a crawl for many of us, which some lucky ones keep dropping 3-4 pounds a week until they are within 10 pounds of goal.
