Patent Claims:	1. A method for treating excessive daytime sleepiness in a subject in need thereof, comprising administering once daily to the subject a therapeutically effective amount of (R)-2-amino-3-phenylpropyl carbamate (APC) or a pharmaceutically acceptable salt thereof, wherein the APC or a pharmaceutically acceptable salt thereof is administered to the subject at least hours before the subject's bedtime. 2. The method of claim 1, wherein the excessive daytime sleepiness is due to narcolepsy. 3. The method of claim 1, wherein the excessive daytime sleepiness is due to obstructive sleep apnea. 4. The method of claim 1, wherein the excessive daytime sleepiness is due to shift work disorder. 5. The method of claim 1, comprising administering a pharmaceutical composition comprising the APC or a pharmaceutically acceptable salt thereof and a pharmaceutically acceptable carrier. 6. The method of claim 5, wherein the pharmaceutical composition is a dosage form. 7. The method of claim 6, wherein the pharmaceutical composition is an immediate release oral dosage form. 8. The method of claim 6, wherein the pharmaceutical composition is a tablet or a capsule. 9. The method of claim 8, wherein the pharmaceutical composition is an immediate release compressed tablet, the tablet comprising: APC or a pharmaceutically acceptable salt thereof in an amount of about 90-98% by weight of the tablet; at least one binder in an amount of about 1-5% by weight of the tablet; and at least one lubricant in an amount of about 0.1-2% by weight of the tablet; wherein the tablet releases at least 85% of APC or a pharmaceutically acceptable salt thereof contained therein within a period of less than 15 minutes after administration of the tablet to the subject. 10. The method of claim 1, wherein the therapeutically effective amount of APC or a pharmaceutically acceptable salt thereof is about 37.5 mg. 11. The method of claim 1, wherein the therapeutically effective amount of APC or a pharmaceutically acceptable salt thereof is about 75 mg. 12. The method of claim 1, wherein the therapeutically effective amount of APC or a pharmaceutically acceptable salt thereof is about 150 mg. 13. The method of claim 1, wherein the therapeutically effective amount of APC or a pharmaceutically acceptable salt thereof is about 300 mg. 14. A method for minimizing insomnia while treating excessive daytime sleepiness in a subject in need thereof, comprising administering once daily to the subject a therapeutically effective amount of (R)-2-amino-3-phenylpropyl carbamate (APC) or a pharmaceutically acceptable salt thereof, wherein the APC or a pharmaceutically acceptable salt thereof is administered to the subject at least 10 hours before the subject's bedtime. 15. The method of claim 14, wherein the excessive daytime sleepiness is due to narcolepsy. 16. The method of claim 14, wherein the excessive daytime sleepiness is due to obstructive sleep apnea. 17. The method of claim 14, wherein the excessive daytime sleepiness is due to shift work disorder. 18. The method of claim 14, comprising administering a pharmaceutical composition comprising the APC or a pharmaceutically acceptable salt thereof and a pharmaceutically acceptable carrier. 19. The method of claim 18, wherein the pharmaceutical composition is a dosage form. 20. The method of claim 19, wherein the pharmaceutical composition is an immediate release oral dosage form. 21. The method of claim 19, wherein the pharmaceutical composition is a tablet or a capsule. 22. The method of claim 21, wherein the pharmaceutical composition is an immediate release compressed tablet, the tablet comprising: APC or a pharmaceutically acceptable salt thereof in an amount of about 90-98% by weight of the tablet; at least one binder in an amount of about 1-5% by weight of the tablet; and at least one lubricant in an amount of about 0.1-2% by weight of the tablet; wherein the tablet releases at least 85% of APC or a pharmaceutically acceptable salt thereof contained therein within a period of less than 15 minutes after administration of the tablet to the subject. 23. The method of claim 15, wherein the therapeutically effective amount of APC or a pharmaceutically acceptable salt thereof is about 37.5 mg. 24. The method of claim 15, wherein the therapeutically effective amount of APC or a pharmaceutically acceptable salt thereof is about 75 mg. 25. The method of claim 15, wherein the therapeutically effective amount of APC or a pharmaceutically acceptable salt thereof is about 150 mg. 26. The method of claim 15, wherein the therapeutically effective amount of APC or a pharmaceutically acceptable salt thereof is about 300 mg. 27. The method of claim 1, wherein the excessive daytime sleepiness is due to depression. 28. The method of claim 14, wherein the excessive daytime sleepiness is due to depression.
