Unstable physical disorders which might make participation hazardous such as hypertension (\>160/90), anemia, active hepatitis or other liver disease (transaminase levels \< 2-3 X the upper limit of normal will be considered acceptable), epilepsy, or untreated diabetes. Participants reporting HIV+ status will be asked to provide information about their current treatment, including all medications. Participants who are on the antiretroviral ritonavir (Norvir) will be excluded due to the possibility that study medications in combination with this medication may increase the risk of drug-induced hepatitis.
• 9. Previous history of misuse or abuse of study medications, and a history of an adverse reaction/experience with prior exposure to study medications
• 10. Recent history of significant violance
• 11. On psychotropic or other medications whose effect could be disrupted by participation in the study
