ADHD
"I am a 20 year old female and have been taking Concerta on and off for five years. I was diagnosed with ADHD during my freshman year of high school. Concerta has worked wonders for me. I started high school getting Ds and Fs and left with As and Bs. I would stop taking it every so often after lowering my dosage to see if I could manage without it but I would almost immediately lose my organization and more importantly my motivation. I did experience some side effects, including appetite loss and insomnia. These were easily cured by a dose modification. I am now the proud manager of a successful business."
