That would have been a hypomanic state. Mania has the psychotic element. I can understand the allure of it. High energy and a flight of ideas, as long as you don't get the irritable mood component or the unwise actions components.

I don't know a way to induce it. That's relatively uncharted territory from what I understand. As the previous poster states, there may be a way chemical route.

Another thought is to remember back to what happened before your last hypomanic state? If you don't have Bipolar II and have a cycle where you switch it may have been an induced state in the first place.
