The only problem I have with CHADD (which my psych dr recommended) is there is a fee to join per year. Same Dr recommended Driven to Distraction.

The books my ADHD Life Coach recommended are:

More Attention, Less Deficit - Success Strategies for Adults with ADHD by Dr. Ari Tuckman (He is having a free discussion on the 29th at addclasses.com)

Is It You, Me, or Adult ADD? (there is more to this title) by Gina Pera

I am getting the first for me, the second for my husband (who is adrift on a sea of estrogen in an ADHD ship as me and both our daughters are ADHD). I'll let you know how those are.

Some sites (mainly for women) that I have found that are good are:
momswithadhd.com
womenwithadd.com (Or ADHD, can't remember right now)

These are run by life coaches who specialize in ADHD.

ADDitude.com - this is a magazine and forum, though the site is not very ADHD friendly with the ads, but it is the price of doing business like that.

Hope this helps!
