When I was pretty close to reaching my goal weight at Weight Watchers, I also was determined to get there FAST...and I did.
Some of the things that helped me were lots of water, a lot of veggies, fat free everything I could find, no nonsense snacks - like fruit, veggies, or a slice of weight watchers bread with fat reduced peanut butter, lean cuisine or weight watcher's tv dinners for supper and Italian ices(made from water) for desert, fat free Kool whip and fat free or sugar free jello (I think they have no calories), lots of coffee,
and walking. I wasn't even hungry I was so determined. You can do this - it's only a bit over 3 pounds/week. If you should reach a plateau and not lose a lot one week or so, keep on going. It's normal.
Good luck
