Weight Watchers Update

I am fully down 30 lbs. YEAH. I want to increase this greatly still. Whenever it comes time to loose a point, I have fast weight loss for a few weeks. Then I go over a month on those last few pounds, they just don't want to come off. I've been looking at ways to try to fix this. Some suggestions have been: decrease the fat intake of the items I eat, exercise, mix up my point intake by spreading out my weekly points, try the CORE plan for a week (a nutritionist friend of ours does this whenever she hits a plateau and says she always looses 4-5 lbs that week, all the other weeks she just does their normal average plan). I finally got below that 29 lb mark by exercising more during that week. 
Define CORE plan: A Weight Watcher's plan that doesn't count daily points. You can eat all the fruits, veggies, pure whole grains (NO FLOURS or ENRICHED ie no refined grains), and lean meats that you want. No non-natural sugars or fats (ie- non that aren't found in the items already said you can eat). You can eat all the Fat-Free dairy you want, and you can use up to 2 Tbs of oil in your cooking a day. You still have your 35 weekly points and that you can use to intake any item that doesn't fit into the above restrictions. Cheese, fats, sugars, ice cream, going out.  My husband has been against doing this. He wants to do it all with out confusing himself on what he can or cannot do. But lately he has also been hitting a hump that he can't seem to get over and is becoming open to trying this for a week. 
So we'll see what we do. I know that 30 lbs is a huge achievement. Of all people who are proud of me, I am so proud of myself. This is a HUGE accomplishment for me. Before counting points I was never able to loose 10 lbs, let alone 30. But my goal is loose it before we go on our cruise in October. Or a more important goal is before the next time we get pregnant. I still have 20-30 lbs to go. That makes me half way. It took me almost 7 months to get to this point. If I am to loose it by the cruise than I have 3 1/2 months or 16ish weeks to loose the rest of it. That's slightly under 2 lbs a week. Which would be healthy weight loss, but I haven't been loosing that fast. I need to do something to help this along. Anyone out there who also does Weight Watchers have any ideas for getting over those humps?
