Plateau

So my weight loss has been slowing down. I'm 161.2, very close to my initial goal of 160. I still want to lose more weight, 150 eventually. I have 2 weeks left of Bernstein and don't think I will make it to my Dr. B "goal weight" of 155 by then. I'm losing about 1-2 pounds a week, which is healthy, and makes sense, as I have a lot less fat to lose. Thing is, you don't qualify for their "4 weeks of maintenance" unless you hit your goal weight. It doesn't make financial sense for me to keep paying for full strict weeks to get the free 4 maintenance weeks, as 1 full week = 6 weeks of maintenance. Kinda stuck now. Will post again!
