What can I expect coming off concerta? How is it done? I don't really see it helping and I'm not sure I have add

Consult prescriber. Concerta can be stopped, even though its long acting stimulant it is out of your system at the end of the day. You and/or people around you will realize if it was helping you within few days. It is important to have a talk with prescribing physician before doing this or if you think you don't have add.
See U prescribing . Physician or take a second opinion from another physician.
