Getting back into weight loss

So I fell off the wagon again..... :( *tear*. After losing about 7 pounds and going down to 171, I gained that all back. I just wasn't as motivated to finish P90x as I thought I would be. I've decided I don't want to be this big muscular body building looking guy and instead to go for a leaner look. So now my aim is about 145 pounds, the weight I was when I first lost weight in high school. I bought the Biggest Loser Wii game and completed my first workout today. I put it on the "Intense" setting and it was definitely intense. I was sweating as much as I did with P90x and all the other exercise programs I've done and I def. got a workout. I'm also watching what I eat now, after realizing that I have an eating disorder of overeating. I think that writing down my feelings and struggles with food and weight will help me achieve better long-term results than in the past.
