Hey folks
I am 32 years old just started concertain march. I am very active. Is there any foods that interact with concerta? I am now on 72 mgs (54 in the morning, 18 in the afternoon) and I dont find a difference for focus just a bit with moodiness.
Any suggestions?

No change at all? You really ought to feel some increase in focus, especially in the AM....

You may want to try 72mg in the morning. I have been doing that for a couple of years. I have never had any problems concentrating (at least throughout the day).
