Carrie Fisher said this quote

I mean, that's at least in part why I ingested chemical waste - it was a kind of desire to abbreviate myself. To present the CliffNotes of the emotional me, as opposed to the twelve-column read.I used to refer to my drug use as putting the monster in the box. I wanted to be less, so I took more - simple as that. Anyway, I eventually decided that the reason Dr. Stone had told me I was hypomanic was that he wanted to put me on medication instead of actually treating me. So I did the only rational thing I could do in the face of such as insult - I stopped talking to Stone, flew back to New York, and married Paul Simon a week later.
