When I switched from 54 to 72 ml of concerta each morning i noticed a big difference in the length of time it was taking to work.i.e. motivation and confused thought process. There's something not the same between the two doses. Although there supposed to be time realesed over 12-18hrs, I beleave the smaller doses are releasing quicker into our system as opposed to the 72 ml dose. I've asked my specialist and he is currently looking into the problem but no solution yet. If he replies i will be sure to let u know the outcome. (I'm a 34 year old male.)

Before switching to Concerta, my dosage for Ritalin was about 30mg every 3 hours during work hours. The inconsistency/variability/ups&downs of this dosage led me to change to 54mg Concerta supplemented by 10 to 20 mg of Ritalin every three hours. I find this works well for me as the Concerta provides a base level effect that is sufficient for easier workloads (ie. meetings, training people, or working at home). For work requiring more focus (writing, budgets, communications), I supplement with 20 mg of Ritalin every 3 hours (ie. 9am, 12pm, 3pm). I like this as I can adjust (reduce) my Ritalin dosage based on my needs for that day while the Concerta provides enough effect to keep me generally productive. When I have to work in the evenings (a little bit too often), I'll take 20 mg Ritalin which is usually sufficient, eventhough the effect of the Concerta has mostly worn off.

I did try two 36mg Concerta once (my son takes one/day - yes, it runs in the family), but didn't like the effect.
