ADHD
"I&#039;m 17 and have been taking this for about a month now for ADHD. I started at small doses of Ritalin (10 mg) and then moved to 20 mg. My doctor thought it would be easier to just put me on Concerta since it&#039;s 18 mg a pill. I then took 36 mg of Concerta which didn&#039;t work out. I got major irritability and started feeling depressed. Even my focus was off. I went back down to 18 mg and it&#039;s working much better. No irritability, depression feeling. Make sure you&#039;re on the right dose for your body, too much can do more harm and too little may not do any thing."
