Ok, but what about quitting smoking triggering insulin problems? It seems that that could cause PCOS or cause mild PCOS to become worse. Before quitting the only symptoms I had were depression, weight problems, and acne. After quitting, I compulsively ate because of my intense carbo cravings--I am not just talking about eating more to "replace" smoking--I am talking about compulsive eating based solely on cravings. All of the extra weight went to my waist and belly. I have always been apple-shaped, but now I am a big apple!!! I was a heavy smoker, and I believe that quitting smoking really affected my insulin production and my metabolism. I have always suspected PCOS, but now I think it is more severe.
