No, speaking personally I don't consciously notice the effects of Concerta. Far from being a high that I crave, I actually have to set myself reminders in the morning and make a ritual/checklist, and I set my medication out on a visible shelf in the bathroom, otherwise I'll forget to take it.

I'm not sure how many people with addictions are regularly forgetting to take their drugs without a phone reminder.

The point of the delay release is that you don't have the same kind of ramp up to extreme effects and then come-down. Instead the goal is to get a (roughly) consistent dose that helps with executive dysfunction, and doesn't do much else. As always, that's something you work out with the help of a psychiatrist, not everyone reacts to methylphenidate the same way.
