I am a 20 year old male - it is now day 5 of consuming 36mg of Concerta. The 2 first days we're fantastic. I was easy going, I would overall say that my focus was good. I felt great/clear and got plenty done.

NOW day 3 up to now - I feel mostly the side effects, such as being irritated, depression, and zombie-like all throughout the day and NO effect of increase on attention.
I'm paying attention as to know if I should continue or try something else or change the dosage.

Is someone else experiencing this with Concerta?
