I have a lifelong binge eating disorder. I used to control my weight with exercise, but 15 years ago, chronic injuries and illnesses (including hypothyroid) slowed me way down, and my weight went way up. I worked really hard through therapy and medications to get it under control, and finally stabilized my diet and lost 30 pounds. This past year, my thyroid meds have been adjusted and the "numbers" supposedly are good. However, after switching from generic to a higher dose of Synthroid a few months ago, I am binging like mad again and gaining weight fast -- somewhere between 10 and 15 pounds (I've lost track!). My mood has lifted, which is a plus, but I still become exhausted too easily, at least partly because of the excess sugar and weight. I have so many confounders, it's hard to tell.

This thread has really helped. I'm glad to know it probably isn't "in my head" but instead is my past binge habits re-emerging as the drug-induced weight gain triggers my deep-seated fears. Time to talk to the doctor again.
