I agree with fletch...try Atkins for a couple weeks to jump start your system, then slowwwwllly increase your carbs to what you're eating now. And the weekend carb increase is probably what's holding you back. Start off at 20, do that for a couple weeks (or until you are closer to your goal), then increase it by 5 grams/week...until you hit goal. Doing this will also show you at what carb intake level you stop losing weight. Hope this helps!
