Wow...12 miles...that's inspiring! On the binging thing...why not just allow yourself a "cheat meal" once a week or once every 2 weeks? I find that allowing myself a cheat meal once a week, erraticates the desire (most weeks) to even cheat. Just knowing that I can, and still lose weight, takes the "taboo" out of my favorites meals (Jamaican Food..yum). The only tip is if and when you have your cheat meal, monitor the sizes and portion. Still get in your proteins with your fats...don't just go crazy with a huge bowl of pasta and bread!!!
On the running tip...I totally identify with you. Now..21 lbs lighter than I was 7 weeks ago...I'm already finding running easier. I'm "bottom heavy" so I think if you have "skinny legs/thighs" it makes running easier. I hope to share a similar end as you when I drop the next twenty.
Again....way to GO!!!!
