I have difficulty concentrating in class, and I've heard that people take ritalin to help them concentrate. Where can I buy some? Can I buy it over-the-counter?
i have ADHD and i used to take that. you have to go to the doctor they will test you if you do have ADHD they will tell you about the meds, there are lots of diff ones the doctor and you will have to decide what one is rite for you!
Go see a physician about your concentration difficulties. Ritalin is prescribed for ADD and related things. Your issue could be something entirely difference. Don't self-diagnose and medicate. Go see a doctor!
