ktsnake, on this at least, we can agree.

And I applaud you for working through your problem rather than popping a pill.
I used to help out with a religious school program that met after school, and we had a number of ADD/ADHD sufferers among the students, most of whom were on Ritalin etc. These parents were faced with a tough choice: to have their child's school nurse give them a dose at the end of the school day, or not. If they didn't get a dose, their dose(s) from earlier in the day would just be wearing off when they got to religious school, and they wouldn't be able to sit still for their lessons. If they
did get a dose, they just sat there like zombies.
I'm not a doctor, but I believe many of these kids were overmedicated. So when the drugs wore off, they exhibited their symptoms a lot more markedly than they might have if they had not been medicated in the first place (or received a lower dose) and had to deal with those symptoms on a minute-by-minute basis.
Sometimes I think the kids are medicated just to make things easier on their parents and teachers.
