"male age 47 adhd sufferer.... been taking concerta xl 36mg for the past 12 years now.. to start with, i didn&#039;t understand how the drug would help me.. but now looking back it has proved to be a fantastic drug that has tweaked the way i live my life.. but i say this with caution, as its not perfect and it caused me a lot of other problems.. like someone has said on here before it doesn&#039;t turn you into a fully focus person. sorry. well it hasn&#039;t for me but it has helped me over time to stop beating myself up on that bloody roundabout in my mind, and gain a little bit of confidence..balance of mind ultimately came when i was prescribed antidepressants.. so i use concerta at 4am and antidepressants at 8pm.."
