Welcome, losetenmore. I hear you about plateaus. I was stuck at 155 for a couple of weeks. It can be discouraging sometimes when you're doing everything (well, almost everything!) right and the weight's not coming off. But even during that plateau I was encouraged by feeling better and my clothes being loser.
I had been keeping calories under 1400/day. When I dropped it to under 1200, I finally broke through that darn 155. But who knows if that was what did it or if it would have happened anyway at that point.
You've got to lose just under 2 lbs a week to meet your goal - very do-able. You lost the first 14 - you sound very committed - you can lose that last 11.
