Back on the Wagon of Weight loss

Options
I'm new to MFP. A girl that I worked with told me about it and that it worked for her last year. I went on weight watchers a little over 2 years ago and it worked...I lost 20 pounds (I was 180 pounds at my high), but lost the motivation to keep on and the money to keep doing it. So now i thought I'd try this. I just bought a wii fit to try to get myself to be more active in a fun way and lose some more weight. A friend of mine is getting married in August and i am in the wedding. My goal is 20 pounds by then. I'm feeling hopeful...
