What happens when you skip three or four days of taking concerta.
Does your personality tend to get in a crazzy mood, or do you just think very slowly and you're mind is confused? (All opinions please)
Also if you have facts please tell me them)

Thanks,

Concerta is an extended release formula of Methylphenidate, the same drug in Ritilan, Metadate, and a few other ADD meds. Methylphenidate is a mild CNS stimulent structurally similar to (but more complex than) amphetamine and methamphetamine. The symptoms you describe (crazy moods, mental cloudiness, etc.) can all be symptoms of amphetamine withdrawl, and I assume they are possible for Methylphenidate as well. Liturature concerning Methylphenidate (in all forms) often bear this warning about the drug: "Methylphenidate is an amphetamine-like drug and can be habit forming, leading to tolerance and serious physical and psychological dependence." certainly no dependence-forming drug should be discontinued abruptly after a long history of clinical use, as many unplesant symptoms (including those you mentioned) may occur. always talk to your doctor about discontinuing any perscription medication.
