I am surprised no one has mentioned Ned Hallowell or the books, Driven To Distraction and Delivered From Distraction. I read the second one when I was 21, recommended and lent to me by a friend with ADHD herself (a sister but moreso a close friend, since we met working as summer camp counselors together, and then I eventually transferred to her college).
That book saved my mental health... it has short, informative chapters, and it's designed for people with ADHD so you can skip around like us ADDers are prone to... but after reading it I realised this was my life written down, and I wasn't alone.
Dr. Hallowell is the preeminent expert on ADHD... he not only has it himself but also suffers from dyslexia (many ADHDers are co-morbid, and will have another disorder alongside the ADHD, or vice versa. I have dyscalculia, which is the numbers equivalent of dyslexia.) and is The Guy who knows the most... annoyingly, his center does not accept health insurance.
I also got ADDitude magazine for quite some time and it helps immeasurably. It's a fantastic resource.
I do advocate meds as long as you can find ones that work for you/your kid. It took me a very long time (mainly due to insurance) to get adderall, which changed my life. I no longer felt dumb... what used to be 3 hours of studying with a small percentile of retention, I could now do in 20 minutes with an extremely high rate of retention.
I know, this reply is all over the place... I'm not medicating for ADHD right now, bc I have much larger fish to fry medically, so it's at the bottom of my pile. If I get back in a situation that requires my attention and focus, I'll get the script again.
Here's the link for the book:
