I realize this topic originated a while ago, but I also feel it may have sparked some worthy discussion.
SnappDragon-
Does the Concerta have the same kind of effects on your ADD as
Ritalin did (apart from the differences that come with a sustained/long acting release vs. immediate effects)? And have you ever taken Adderal or Adderal XR?
Like
getreal, I concur that both Adderal and [methylphenidate] can have totally different effects.
Ritalin works amazingly well for me, except that I need 20-30mgs of it for each 3-4 hours I have to be "on task." With
Ritalin, I am aware and can multitask quite easily. I am interested in trying Concerta - if only to be taking less in total/day mgs. of Methylphenidate. I have noticed personally for me that Adderal (XR) does not work quite the same - I am able to organize and focus my thoughts quite well but for some reason still get extremely sidetracked and then put my time into something less important

The other drawback is that I only get about 4 hours out of it, which probably starts 1.5 hours after I take it.
The Adderal might work well for days when I have to sit in a three hour lecture or work steadily on research, but for now (with the go ahead of my dr.) I am working to see how I can make them complement each other (sigh).
It actually frustrates me knowing thatADD meds are something I will always need, especially as I continue through higher ed and into my discipline.
