Sorry about your long stall - how frustrating! A couple of questions: Is your original goal weight a realistic weight for your height and age? It's possible that the reason you couldn't lose that last twenty pounds is that, like it or not, you were at your ideal body weight. Second question - have you been tested for possible thyroid disfunction? I believe this becomes more common as we grow older, maybe it happened as you were losing, even though not as a result of it.
