adhd
"I'm 19 and I've been on Concerta since age 7 . It has helped me no doubt. I have never had any problems as people say above stomach problems I have never had any. The only thing is I keep eating the complete opposite of everyone else. I usually take it at 9am everyday and I notice it wearing of around 6pm. Yesterday I didn't take because I tried something. I'm currently working night shift usually it's been out of my system hours before starting work. So tonight I took it 9pm even though now it's 4.30am and I've been awake since 7am yesterday I neither show or feel any signs of being tired, drained both physically or mentally. This medication has been nothing but a Success for me."
