adhd
"My 6 yo son was only on this 10 days before yanking him off of it. The first day he ate almost nothing, threw up by 5pm and was awake at least 3 hours after putting him to bed. That day and the next few days he talked incessantly and had dry mouth, but his ability to attend in school was a little better but only for maybe 4 hours tops. By the last 3 days, it was making him worse. He was very irritable and was literally bouncing off the walls, and made his impulsiveness even worse. He was crawling on the floor, biting his nails wildly, licking things...you name it. This was a kid that most other people never even knew had issues, but within a week on Vyvanse, he was definitely acting wild."
