Another question is if the doctor actually DIAGNOSED you with ADD, or if he just mentioned that you may have a mild case of it. My understanding is that a true diagnosis of ADD is quite involved. A quick search shows that a true diagnosis includes:
Technically, to be diagnosed with ADHD inattentive type, adults (age 17 and older) must have:
Five or more symptoms of inattention (see symptoms); symptoms can change over time
Symptoms must be present for at least 6 months
Symptoms must interfere with or reduce the quality of social, home or work life
Several symptoms were present before the age of 12
Several symptoms are present in at least two major areas of your life, for example, work, home or social life. Some examples might be job loss due to inattention symptoms or financial problems caused by poor organization or failing to pay bills on time.
Symptoms are not due to another mental disorder
If you were not officially diagnosed then....well you weren't diagnosed with it.
