  3. Subjects must have moderate-to-severe hypomania or mild mania within the past 2 weeks, defined as having a YMRS >10 and < 21 at the baseline assessment.
  4. Subjects' overall bipolar symptoms must be clinically significant but not greater than severe (defined as a CGI-BP >2 and < 5).
  5. Subjects must be outpatients.
  6. Subjects must be on no psychotropics for 1 week (2 weeks for fluoxetine and 4 weeks for depot antipsychotics) except for prn lorazepam (.5-2mg/day) or zaleplon (5-10mg qhs).
  7. Subjects or their legally authorized representative must sign the Informed Consent Document after the nature of the trial has been fully explained.

Exclusion Criteria:

  1. Subjects who do not have bipolar disorder by above DSM-IV-TR criteria.
  2. Subjects whose bipolar symptoms are more than severely ill (CGI-BP > 5, YMRS > 21, or IDS > 39).
  3. Subjects who are receiving treatment with an antimanic or mood stabilizing medication (lithium, valproate, or an antipsychotic), and in the investigators' judgment, require ongoing treatment with that medication.
  4. Subjects who require hospitalization.

  8. Subjects with serious general medical illnesses including hepatic, renal, respiratory, cardiovascular, endocrine, neurologic, or hematologic disease as determined by the clinical judgment of the clinical investigator. Subjects with hypo- or hyperthyroidism unless stabilized on thyroid replacement > 3 months.
  9. Subjects who are allergic to or who have demonstrated hypersensitivity to any valproate or divalproex preparation.
