As far as treatment -- stimulants help absolutely everyone focus better, regardless of whether or not they have ADD. I am not exception. My personal belief is that ADD is mostly just a catch-all term for people at the lower end of the spectrum of focusing.
My advice as far as medication is to get Ritalin or Focalin or Concerta, not one of the amphetamine based drugs. Don't bother with the non stimulant drugs. Amphetamine (Adderall, Vyvanse, Dexedrine) is a very serious, hard drug to be taking every day and it can do odd things to your ability to experience pleasure.
I am prescribed twice daily short acting Ritalin 20mg, though depending on how much I want to focus I take it less often and/or in a lower dosage. If your schedule is flexible and you know you don't want to be stimulated for 12 hours at a time, then ask your psychiatrist for a short acting medication rather than one of the extended release ones.
Finally, you should always get mental health advice from a mental health professional. Please see a psychiatrist, not your primary care physician.
