Hey, DS,

It only takes ONE manic episode to diagnose bipolar I. Sleeplessness, delusions of grandeur, reckless behavior (sex, money), feeling like you can do ANYTHING!!!! These symptoms last at least a week (according to DSM-IV). Look up DSM-IV, you can check out the criteria for yourself. Shorter duration or less intense is usually hypomania. That will usually lead to a BP -II diagnosis. Becoming manic/hypomanic after an antidepressant is a classic symptom.

Keep a mood chart, see your pdoc. Good wishes!
