I have also been doing a lot of positive self talk. It is amazing what happens,when you tell yourself that you are thin, happy and self confident, while you are in the process of losing. I have been listening to the CD's of "The Secret" the past 3 weeks. If you don't know about "The Secret" you need to google it and read about it. It may sound strange, but I know it works. I can feel it working in my life.
Stay strong and remember to say nice things about yourself. What you think is what you will become.
