My heart goes out to you. Sounds like you are doing what you need to do to save your career.
Over the years, I have spoken with a few career military people who were successful despite being unable to take medication.
I want you to know that you have options other than medication.
There are nutritional supplements that may be helpful. A good book to read on this subject is Your Miracle Brain by Jean Carper. I personally take a multi, B-complex, C, E, calcium with magnesium, D, and K, fish oil and selinium. I think the B-complex, fish oil, and selinium help the most. I've heard other people describe good results with grape seed extract or blue green algae. Taking a multi is important because vitamins are synergistic.
Also worth exploring are specific amino acids. I'd seek the guidance of a naturopath if I went this route.
There are also nutritional formulations specificially developed to treat ADD that are available through the internet. I don't take them because the above regimen meets my needs, but I encourage you to do your own investigation. My only advise is to seek quality supplements. Go to www.consumerlabs.com for more information.
Neurofeedback is another option, but it's expensive and requires a significant time commitment.
After a quick search on the internet, I found this article http://www.dbpeds.org/articles/detail.cfm?TextID=%20758. I think it provides a good overview of what you're potentially up against.
Keep us posted,
