I have Binge Eating Disorder so my Psychiatrist prescribed me Topamax 300 mg daily. It has been working great for appetite control. Been on it for a couple of months now. Both months though, I have experienced PMS symptoms such as insatiable hunger right before the period. Unfortunately, this didn't just last for a few days. It was a full 14 days. From what I've read it is high progesterone levels that cause this. I have an appointment with an endocrinologist at the end of this month that can hopefully get things straightened out. Advice would be greatly appreciated!
