Patent Claims:	1. A method of treating excessive sleepiness in a human patient with obstructive sleep apnea (OSA) in need thereof, said method comprising orally administering [R]-2-amino-3-phenylpropylcarbamate (APC) or a pharmaceutically acceptable salt thereof to the human patient in accordance with a dosing regimen comprising a once-daily dose of 75 mg for at least 3 days followed by a once-daily dose of 150 mg, wherein the once-daily dose of 150 mg is the maximum dose in the dosing regimen, and wherein the APC or pharmaceutically acceptable salt thereof effects a reduction in excessive sleepiness as measured by Epworth Sleepiness Scale (ESS) score to below 10 points at the 12th week of the dosing regimen. 2. The method of claim 1, wherein the dosing regimen comprises a once-daily dose of 75 mg for 3 days followed by a once-daily dose of 150 mg. 3. The method of claim 1, wherein the patient with OSA has a baseline ESS score greater than 10. 4. The method of claim 1, wherein the APC or pharmaceutically acceptable salt thereof effects a reduction in excessive sleepiness as measured by ESS score by at least 5 points at the 12th week of the dosing regimen. 5. The method of claim 1, wherein the excessive sleepiness is excessive daytime sleepiness. 6. The method of claim 1, wherein the APC is provided as a pharmaceutically acceptable salt of APC. 7. The method of claim 1, wherein the APC is provided in the form of APC hydrochloride salt. 8. The method of claim 1, wherein the daily dose is administered at least 10 hours before the patient's bedtime. 9.
