That worked, so I stuck with it.

If you don't feel any difference, it might not be the right treatment for you. Adderall is not like an antidepressant where you have to continue use for weeks before you feel results - it should be immediately apparent if it's going to help (thus why some people abuse it for energy or to help them study for an exam or just to get high, because it can be taken at random for the same effect without having to build up in your system).

Have you tried any other drugs? You should ask your doctor and see if he'll try putting you on either a different dosage/extended release or a different drug entirely.
