I'm a post-first-weight-gain-in-ten-years, post-obsessing-about-food-every-minute-of-every-day, and life is different. It really is. I still struggle sometimes, but I can honestly say that the tapes are no longer playing. Once in a while I hear a little “commercial,” a brief ten-seconder: Are you sure you don't want to lose a little weight? Wouldn't you rather skip that high-fat meal?
