are hard to live with. They also are limited, in time and effect.

Studies show that kids' brains change with age, and stimulants
no longer work after a time.
example:

We found that natural interventions worked much better for our son. At the time, these were still new, and mostly I was attacked and flamed for bringing them to others' attention.
Now they are mainstream, and worth looking into.

Males and esp people on stimulants need zinc. Also EFAs work well. I have an EFA thread here at the Vitamin forum.

Since the behavior problems occur when the drugs wear off,
that sounds like rebound to me. There is not much you can do with rebound, but endure it. It is not the kid's fault..so don't get discipline oriented for those times.

Natural solutions include:
EFAs (Omega-3's esp DHA)
magnesium
zinc
Bcomplex or at least B6.

B6 and magnesium are needed to make serotonin from EFAs.
Since transfats are being removed from foods now, they are less of an issue. But a diet high in them is not good, as they displace the necessary Omega-3s from being used properly.
If you Google around you can find reputable places with advice, (and some strange stuff too).
