I hit my all time low of 220.8 on 08/13/09. And then have bounced back and forth between 224 & 221 since then. Finally last week, I took a good hard look at what I'd been doing in the last 4 weeks and realized I'd been goofing off. I'd lost almost 20lbs since June 8th. I hit that 220.8 and just slacked.
I wasn't working out as much as I had been. I was definitely not eating as well as I was for the first 2 months. My weekends were a nightmare of salty fried foods, alcohol, and chocolate (Twix will be my downfall 
), but I thought since I was eating so well for 4-5 days a week, it would offset my bingey weekends. I actually considered that I hit a "plateau". Uh, that was clearly WRONG! So on 09/07/09, I totally recommitted. And by Friday, I was down to 220.0.
Last weekend I really watched what I ate. I splurged slightly but nothing insane and today I am down to 218.6. But, there is something strange that clicks in me when I hit a new low.
I don't know what it is, I'm guessing some form of self-sabotage. I've been trying to figure out what happened in the last 4 weeks so it doesn't happen again, you know? Does anyone else go through this? I mean, I am super super happy to be at 218.6. It's crazy how happy I feel right now. 
But why do I also feel this anxiety building in me?
Keep up the great work!
