Sauravu,
Windarra makes a good point with diet. It has been shown that sugar, caffeine, and processed foods contribute to ADD symptoms. In todays society we are bombarded with bad dietary choices from fast food, processed foods, high fructose corn syrup, food dyes etc...You may have already considered this. Fortunately, we also have an abundance of healthy choices if we are careful and know how to look for them. With your exposure to the Hindu backround, perhaps you've already explored the ayurvedic perspective on nutrition based on your dosha.
Many people diagnosed with ADD seem to be "right brained" people which can have many positive attributes such as creative thinking, above average intelligence (which is reflected in your job position).
I am sure that AYP will help smooth out some of the bumps in your consciousness. If you can establish a habit of AYP, I believe that your mind will have a difficult time "trashing it". Give it time to take root into your psyche. Establishing the habit may be the difficult part. Once things take hold things will smooth out.
Best of luck to you and let us know how things go.
With Peace,
Paul
