my XH had ADD (totally out of control a lot of the time which is one of the reasons he's now a XH), but when he was willing to take responsibility for it, we pretty much had it under control. He had it from a child, his parents used to just medicate him (and use him having ADD as an excuse for his behaviour - his mother still does it to this day - or did last time I spoke to her which was about a year ago) instead of helping to give him coping strategies and do other things to manage it. (a good friend of mine was diagnosed with ADD as a child, his parents got him into meditation and things like that - he is now a university professor with a phd)

I found that by cooking most of our foods from scratch, reducing the amount of "junk" and take-awy that he put into his body that he was more "in control". I also made sure he had fish oil every day and a decent multivitamin. When I went through a period of us just eating organic it was like I was married to a normal person! He also was prescribed dex-amphetamines which did help him when he took them.

There is a good book that my x-mil gave me about ADD & ADHD in adults, if I can find it (don't' know if I kept it when we split) I can send it to you - I don't need it any more.
