I can say for sure that Vyvanse can *cause* something like binge eating – it reduces one’s appetite all day. However, the medicine wears off in the evening (it has to, or else the person taking it will be up all night) which can cause make-up eating to recoup those lost calories. To many this looks like “binge eating”. I actually gained weight since I started Vyvanse 6 years ago, as it shifted most of my food intake to the evenings and night. That also happened (but without weight gain) to my ex-husband who has been a bit underweight his entire life – he now “binge eats” every night, as he describes it. I also think BED is not a real “disorder” but a result of restriction dieting, so recommending a drug to “treat” it is already stupid, yet not surprising that its a med that can actually exacerbate the symptom.
