One of my relatives has ADD, he's only 7 and behaviour wise, I think he just needs a good kick in the arse. But he does get distracted very easily, and the medication does seem to be helping him with that, but his behaviour is still shit.
When he arrives at school, as soon as he walks in the door the teacher asks him if he's had his medicine and if he says no then she gets straight onto the phone and calls his mum. "Yeah, he's just a little unsettled, he said he hasn't taken his medication so would you be able to...etc"
Teachers these days are fucking useless.
