Mini withdrawal : Concerta is a habit forming stimulant. So like other substances when someone tolerant to the drug misses it they can feel the opposite effects like fatigue drowsy

Take meds every day: Concerta is a medicine that needs to be taken every day, seven days a week, all year long. It's not an as needed medicine. We all need to function and concentrate every day. If you skip a day, you may go through withdrawals, and then the next day, your body isn't used to the dose, and you have side effects.
