Vyvanse
"I'm 17 and on 60 mg of Vyvanse. I weigh about 112 lbs. I don't know if it's too high a dose, but ever since I got it increased from 50 to 60mg. I've been feeling actually tired, which is a surprise to me because it's a stimulant. I've also had more intense dizziness and headaches, and I had heart palpitations on the 50, but now they're more frequent, and chest pain, heart races, but I'm able to focus a little better."
