Bonkerz - we're in a similar position with DS1. He's only 6, but is having such issues with his ADHD and with Anxiety and is so oppositional.
Anyone who doubts the existence of ODD has never met a child who will quite aggressively reject something he likes and wants because he suddenly realises that a parent or teacher approves of the fact that he wants it, which makes it no longer something in his power, causing a panic reaction.
They've never met a child who won't eat that they love because the fact that it is lunchtime at school or home at x time is an imposition on their will and sends them into a blind panic.
DS1 is currently playing quietly with sticklebrix (thank goodness). He didn't accept them when I offered them to him, because it wasn't his idea. I gave them to his brother, instead, which made them desirable.
I'm currently keeping a behaviour diary for DS1 and today is very long, already. This is the first time I've gone an hour without a negative entry. The boys are back at school tomorrow and DS1 is very hyperactive and rather volatile and has been doing some serious button pushing. It's like living with a drunk and, I suspect, not much fun for him, in reality, even though he's been doing a lot of manic giggling. We have to deal with this all too frequently and could really teach Supernanny a thing or two.
I did watch the program, last night, thinking that all the outbursts were so wonderfully calm and restrained and free of tears and red faces and people getting physically hurt. If the right drugs can make that difference for DS1 (who is currently part time at school because he's struggling so badly), then I'm all for it.
