I see lots of people here talk about stalls a few weeks out and beyond. Here is an interesting link to help you process what is going on:

This is helpful, I came on the forum today to look for information about stalls/plateaus, so the timing of this was great! :-) I have about 20 lbs. left to go and I'm definitely struggling. My weight has been virtually unchanged for the last three weeks. I think it's definitely time to add some additional workouts to the mix and also document (more closely) what I'm eating. I know that the closer you get to your goal weight, the harder it can become to lose. I'm hoping to be able to welcome 2012 at my goal weight.
