7. The method of claim 6, wherein the disorder or condition is attention deficit disorder, attention deficit hyperactivity disorder, excessive daytime sleepiness, major depressive disorder, bipolar depression, negative symptoms in schizophrenia, chronic fatigue, fatigue associated with chemotherapy or binge eating disorder.

9. The method of claim 6, wherein the central nervous system stimulant is amphetamine or a pharmaceutical salt thereof.

10. The method of claim 6, wherein the central nervous system stimulant is dextroamphetamine or a pharmaceutical salt thereof.

11. The method of claim 6, wherein the central nervous system stimulant is lisdexamfetamine dimesylate or a pharmaceutical salt thereof.

12. The method of claim 6, wherein the effective amount is from 5 mg-54 mg.

13. The method of claim 1, wherein the disorder or condition is attention deficit disorder or attention deficit hyperactivity disorder.

14. The method of claim 13, wherein the effective amount is from 5 mg-54 mg.
