I just started taking 30mg of Vyvanse in the morning to treat Binge Eating Disorder. I took my second dose at 9am and it's 3:30pm now and I feel like it's "wearing off." The first four hours or so were great. I was focused, energized, could eat breakfast and lunch without overeating. I haven't obsessed about food all day, but now I am obsessing A LOT, and my head is achey and I'm irritable and anxious.

Looking for feedback from anyone who has experience with taking Vyvanse for BED. Is this common when just starting to take Vyvanse? Will these symptoms improve?
