Medications should be discontinued such that the subject has returned to his/her baseline level of daytime sleepiness at least 7 days prior to the Titration Phase, in the opinion of the Investigator.
16. Use of a monoamine oxidase inhibitor (MAOI) in the past 14 days or five half-lives (whichever is longer) before the Titration Phase, or plans to use an MAOI during the study.
