Anticipation

Tomorrow is the big day; the day Blaise goes in to be evaluated for ADD/ADHD. The need for this test has become clearly apparent over the last two years (at least). I have to drop him off at the testing center at 9:00 a.m. with a box lunch and the test should take 4-4 1/2 hours. In preparation I had to fill out a long questionnaire with all sorts of questions about his behavior, attitudes, general health and relationships. His intelligence isn't in question because we know that he is clever and his IQ test confirmed that with a score just a couple points below "gifted".
I just want some answers to how we can help this kid settle down and not drive himself and others crazy.
