Thanks for everyone's responses
Has anyone tried caffeine? I've read a couple of article which suggest that it has a similar effect to the stimulants in prescribed medication but obviously it isn't so strong. I'm wondering if experimenting by giving him a double shot of espresso before school would be really irresponsible parenting

I guess the thing I'm struggling with is the fact that there is no 'cure' or 'fix'. That it's almost as much a personality type as it is a learning disorder. I'm a bit masculine in that I hate it when things can't be fixed with actions.

I have a pile of books about 2 foot tall that I got out of the library today but I suspect I won't find the answers I seek in them.

I'm also struggling a bit with his current teacher in that I suspect that she wants him fixed up so that he is quiet and compliant and she wants me to do that. The paediatrician we are seeing is wonderful and he gave me a sheet of classroom strategies for her but I suspect that she won't use any of them.
