Effects of Concerta

I've recently started taking Concerta to try and help with my ADD.  I was wondering what some of the effects people have had.  I don't seem to have a great effect on my true mental ability, just seem to be hyped up, but not in a caffeinated way.  That, and I believe I've noticed that it tends to make me feel more emotional.  I can find myself allowing thoughts to well up and almost push me to crying (for the record, I'm the kind of person who all but never cries).  It's really odd.  I was wondering if anyone else had had this effect?  Honestly, I'm pretty close to stopping using it and trying something else, but I don't want to become a pill-jumper.  I HATE taking meds at all, but I know/understand that it can help me.
