I got REALLY manic about two years ago (2-3 hours sleep a night) & was speed walking about 4-6 hours a day. I also joined Weight Watchers (now known just as WW) & got really compulsive about using as few daily points as I could. I lost about 80 pounds in six months. About six months later, after a long depression, a period of sloth & having my APs kicked up, I gained back much of what I lost. I've got to do something about losing weight again. I had so much energy when I was lighter (& manic ).
