I've been doing some positive thinking as I am going to sleep at night, & also some random times throughout the day. I also do positive thinking during exercise, since exercise always makes me feel positive about myself anyways. The "mantras" I've been using so far have been: "I am lean, I am healthy, I am strong. I am 165 lbs, I am a size 10." I usually do these before bed, in the shower, sitting at work, or anytime I find myself with a free moment. Just find out when works best for you.
