Hi and welcome!
Good for you to be seeing someone who specializes in both ADHD and gifted. Ditto on what others have already suggested about structure and helping your son.
One approach you could try is to go the nutritional/biomedical route. Many parents say that supplementing with Omega 3s (fish oil) can help with focus and concentration. Have him tested for allergies (IgG and IgE testing). Look for connections that might be present in terms of patterns of behaviors associated with exposure to different foods or other potential "toxins." A good resource for this is the book "Healing the New Childhood Epidemic"

http://www.amazon.com/Misdiagnosis-...mp;s=books&qid=1224945908&sr=1-1Something else to consider is that ADHD drugs have made advances and there are many different ones out there, some that are even non-stimulant. If you reach a point where you want to try meds you can always do a trial and then stop if it is not working or making things worse. Some children I work with actually ASK for their meds because they make them feel better and more focused. If meds work for helping a child function better in terms of focus and concentration, task completion and social interaction then I say it is no different than a child with diabetes who needs insulin. Meds for ADHD are not as scary as you might think and for some children (and adults) are the right answer.
