ADHD
"I am a 20 y/o girl. I was on 54 mg of Concerta once a day. This drug was the worst thing thats ever happened to me. It did help my grades but I felt most of it was placebo and the fact that the side effects were so horrible I wanted to focus on work to distract myself. It made my anxiety unbearable and constant. My heart beat in my head. My whole left arm and pinky would feel numb and prickly. I knew I was hungry but could not eat and was disgusted by food. I fell into a horrible depression and felt just overwhelming darkness. The pros was that it made sitting in long classes and retaining information much easier. I felt excited about learning and getting work done. Overall it helped with school but the side effects are not worth it."
