• Have taken any investigational therapy within the 30-day period prior to the initial screening visit for this trial.
• Are routinely taking any stimulant medications, sedative hypnotics, tranquilizers, antihistamines (except for non-sedating antihistamines), benzodiazepines or clonidine at the start of the study. Patients taking anticonvulsants are not eligible to participate even if they are willing to washout anticonvulsants for the trial.
• Regularly consume alcohol and are unwilling or unable to totally abstain from alcohol use for the trial duration.
• Are experiencing any major illness, including unstable cardiovascular, endocrine, neoplastic, gastrointestinal, hematologic, hepatic, immunologic, metabolic, neurological, pulmonary, and/or renal disease which would place the patient at risk during the trial or compromise the objectives outlined in the protocol.
• Have psychiatric disorders, major affective or psychotic disorders, or other problems that, in the investigator's opinion, would preclude the patient's participation and completion of this trial or compromise reliable representation of subjective symptoms.
• Have a current or recent (within one year) history of a substance use disorder including alcohol abuse as defined by the DSM-IV.
• Have a serum creatinine greater than 2.0 mg/dL, abnormal liver function tests (SGOT [AST] or SGPT [ALT] more than twice the upper limit of normal), or elevated serum bilirubin (more than 1.5 times the upper limit of normal), or pre-trial ECG results demonstrating clinically significant arrhythmias, greater than a first degree AV block or a history of myocardial infarction within the last six months.
• Have an occupation that requires variable shift work or routine night shift.
