"When I was about 13 the school psychologist who I was seeing for behavior problems suggested to my mother that I start taking Ritalin. I was hyperactive, could not focus, blurted things out, and was generally viewed as a weirdo by my peers. My mother refused to follow the psychologists advice because she "didn't want me on medicines". 
The same diagnosis and suggested treatment followed the next year and the year after by the Psychiatrist who I was referred to.
Eventually I dropped out of school, somehow managed to get my GED and enroll in college. I decided a few years ago to see a doctor and he prescribed Concerta.
I am now able to follow through on projects and not feel like a failure, frustrated all the time. It has really worked for me."
