Medication is likely not the right solution for you, there are several very helpful books about Adult ADHD that you should check out that could change your life: Taking Charge of Adult ADHD, and, Is it You, Me, or Adult ADHD?
great books
My two cents, don't rule anything out. I had a SO with adult ADD and medication made a world of difference. That's just one person, though, and everybody's different. Do talk to a doctor if you feel like you might have adult ADD. It's a very real thing, and there are lots of treatment options, both pharmacologic and not.
