"i am 26 years old and having been using concerta for approximately 9 months. i have been extremely impressed with my new ability to focus and attention to detail. i have always been a daydreamer and that paid off in creativity.  however, daydreaming during a meeting with the president of the company you work for doesn&#039;t pay off.  my wife, out of angst, suggested that i might have adhd and should consider getting tested.  after a 5 hour psychological evaluation it was decidedly so.  since i have started concerta i have been promoted to the top position in my office.  it controls my anxiety and keeps me calm and focused.  the only side effects that i have noticed are weight loss (lost 30 lbs) due to loss of appetite and a lack of emotion."
