I knew I was a manic depressive when I was 13 or 14, and I loved it. I always told people what I had, and I was always cresting on a manic wave. I used it, willingly and happily, and it was an extraordinary experience. When I got hit with the depressive side - Boom! - yes, it was horrible and unendurable, but that's part of the story.
